Subject: [PATCH] Migrate Vite SPA to Hugo (hugo-coder, dark) with WebGPU
 background

- Hugo static site at root: config, content (home/about/resume/blog + 5 projects),
  data/resume.yaml, custom layouts (gpu background, resume renderer, projects list),
  dark theme with canvas behind content
- gpu-bg/: extracted WebGPU/WebGL2 spiral engine as a Vite sub-package; slim bootstrap
  drops router/overlay/text renderer; fixed uniforms (scene0/dim0); self-contained engine.js
- archive/: retired Vite SPA preserved (router, overlay, data, engine/text orphaned)
- 3-stage Dockerfile (node -> hugo extended/dart-sass -> nginx), static nginx config
- DEPLOYMENT.md handover + README rewrite; pre-hugo rollback tag

+# WebGL Fallback Renderer Implementation Plan
+
+> **For Hermes:** Use `opencode` CLI to implement this plan task-by-task. Each task is self-contained and should be verified before moving to the next.
+
+**Goal:** Add a WebGL2 fallback renderer so devices without WebGPU still get an animated procedural background behind the DOM overlay, instead of a static error message.
+
+**Architecture:** A new `GlRenderer` class mirrors the existing `Renderer` interface (init, render, resize, ready). `app.ts` tries WebGPU first; if that fails, it falls back to WebGL2. Only if both fail does the `#fallback` static message appear. The DOM overlay (nav, content, projects, resume) runs identically regardless of which GPU backend is active — no overlay code changes.
+
+**Tech Stack:** TypeScript, WebGL2 (GLSL 300 ES), UBO for uniform passing, Vite `?raw` imports for shader source.
+
+---
+
+## Current state recap
+
+| File | Role | Change needed? |
+|------|------|:---:|
+| `src/engine/renderer.ts` | WebGPU-only renderer; checks `navigator.gpu`, returns false if unavailable | Extract interface |
+| `src/engine/shaders/fullscreen.wgsl` | WGSL fullscreen-triangle fragment shader (spiral + dim) | None (reference for GLSL port) |
+| `src/app.ts` | `App.start()` calls `renderer.init()`, returns false on failure → site dead | Try GL on GPU fail |
+| `src/main.ts` | Shows `#fallback` div + hides canvas when `app.start()` returns false | Adjust: keep canvas visible for GL path; only show fallback when both fail |
+| `index.html` | `#fallback` div (`display:none`), `#gpu` canvas, `#overlay` div | Remove or update fallback message text |
+
+---
+
+## Task 1: Define shared renderer interface
+
+**Objective:** Extract a structural interface so both `Renderer` and `GlRenderer` are interchangeable in `app.ts`.
+
+**Files:**
+- Create: `src/engine/types.ts`
+
+**Step 1: Create the interface file**
+
+```ts
+// src/engine/types.ts
+import type { UiState } from './renderer'
+
+export interface RendererLike {
+  readonly ready: boolean
+  init(canvas: HTMLCanvasElement): Promise<boolean>
+  render(state: UiState): void
+  resize(): void
+}
+```
+
+Note: `UiState` is already exported from `renderer.ts`. Keep the import there; this avoids circular deps because `types.ts` only imports a type.
+
+**Step 2: Verify**
+
+```bash
+npm run typecheck
+```
+Expected: PASS (no usages yet, just the file existing).
+
+---
+
+## Task 2: Make `Renderer` conform to the interface
+
+**Objective:** Ensure `Renderer` already satisfies `RendererLike` (it does — just verify typecheck passes when assigned).
+
+**Files:**
+- Modify: `src/engine/renderer.ts`
+
+**Step 1: Import the interface and add a type assertion test**
+
+No code changes needed to `Renderer` itself — it already has `ready`, `init`, `render`, `resize`. Just verify:
+
+```bash
+npm run typecheck
+```
+Expected: PASS.
+
+---
+
+## Task 3: Create GLSL fullscreen shader
+
+**Objective:** Port the WGSL spiral shader to GLSL 300 ES (WebGL2). Same visual output: spiral arms, mouse distortion, scene-based palette, dim factor.
+
+**Files:**
+- Create: `src/engine/shaders/fullscreen.glsl`
+
+**Shader content (vertex + fragment in one file, split on marker comments):**
+
+```glsl

+
+    float ringWave = sin(radius * 12.0 - (time * 1.5));

+    vec3 secondaryRings = cardGrey * ringMask * 0.4;
+
+    float vignette = smoothstep(0.95, 0.4, radius);
+
+    vec3 finalColor = bgGrey + secondaryRings;
+    finalColor = mix(finalColor, primarySpiral, 0.85);
+
+    float centerLight = 0.015 / (radius + 0.02);
+    finalColor += centerLight * coreWhite;
+
+    // soft cursor glow
+    finalColor += exp(-distMouse * 4.0) * 0.03 * sceneAccent;
+
+    // dim when not on the home page (date.x controls it)
+    float dim = date.x;
+    finalColor = mix(finalColor, vec3(0.0), dim);
+
+    outColor = vec4(finalColor * vignette, 1.0);
+}
+```
+
+**Key porting notes:**
+- `select(a, b, cond)` → `if/else` chains (clearer than mix-with-bool-cast in GLSL)
+- `array<vec4<f32>, 8>` → `vec4 stemMultipliers[8]`
+- `@builtin(position)` → `gl_Position`
+- `@location(0)` → `out vec2 vUv` / `in vec2 vUv`
+- Uniform buffer layout with `std140` matches the Float32Array layout exactly (vec2 + float + float = 16 bytes, then 8 bytes padding, then vec4 — same as the TS array d[6],d[7] being zero)
+- `atan2(y, x)` → GLSL `atan(y, x)` (same signature)
+
+**Step 2: Verify the file exists**
+
+```bash
+wc -l src/engine/shaders/fullscreen.glsl
+```
+Expected: ~108 lines.

+
+## Task 4: Create `GlRenderer` class
+
+**Objective:** Implement the WebGL2 renderer that mirrors `Renderer`'s lifecycle.
+
+**Files:**
+- Create: `src/engine/gl-renderer.ts`
+
+**Step 1: Write the GlRenderer class**
+
+```ts

+```
+
+**Step 2: Verify**
+
+```bash
+npm run typecheck
+```
+Expected: PASS. The GLSL import via `?raw` is a string; the `RendererLike` import is a type; all WebGL2 types are in the standard DOM lib.
+
+---
+
+## Task 5: Wire fallback logic in `app.ts`
+
+**Objective:** `App.start()` tries WebGPU → falls back to WebGL → only returns false if both fail.
+
+**Files:**
+- Modify: `src/app.ts`
+
+**Changes:**
+
+1. Add imports at top:
+```ts
+import { Renderer, UiState } from './engine/renderer'
+import { GlRenderer } from './engine/gl-renderer'
+import type { RendererLike } from './engine/types'
+```
+
+2. Change renderer field type:
+```ts
+private renderer: RendererLike = new Renderer()
+```
+
+3. In `start()`, change the init block:
+```ts
+let ok = await this.renderer.init(this.canvas)
+if (!ok) {
+  this.renderer = new GlRenderer()
+  ok = await this.renderer.init(this.canvas)
+}
+if (!ok) return false
+```
+
+That's it. The rest of `app.ts` (resize, loop, render calls) works unchanged because both renderers satisfy `RendererLike`.
+
+**Step 2: Verify**
+
+```bash
+npm run typecheck
+```
+Expected: PASS.
+
+---
+
+## Task 6: Adjust `main.ts` fallback behavior
+
+**Objective:** Only show the static `#fallback` div when BOTH WebGPU and WebGL are unavailable. When WebGL succeeds, the canvas is already visible and rendering — no action needed.
+
+**Files:**
+- Modify: `src/main.ts`
+
+**Current code (lines 1-16):**
+```ts
+import { App } from './app'
+
+const canvas = document.getElementById('gpu') as HTMLCanvasElement
+const fallback = document.getElementById('fallback') as HTMLElement
+
+async function boot(): Promise<void> {
+  const app = new App(canvas)
+  const ok = await app.start()
+  if (!ok) {
+    fallback.style.display = 'flex'
+    canvas.style.display = 'none'
+    return
+  }
+}
+
+void boot()
+```
+
+**New code:** No structural change needed — the logic is already correct. When `app.start()` returns false (both GPU and GL failed), the fallback div shows. When it returns true (either backend works), the canvas is visible and rendering. No changes required.
+
+**Step 2: Update the fallback message in `index.html`**
+
+Change the `#fallback` content in `index.html` to mention WebGL too:
+
+```html
+<div id="fallback">
+  <div>
+    <h2>Graphics not available</h2>
+    <p>Your browser doesn't support WebGPU or WebGL. Open this page in a recent Chrome, Edge, or Firefox.</p>
+  </div>
+</div>
+```
+
+**Step 3: Verify**
+
+```bash
+npm run typecheck
+```
+Expected: PASS (no TS changes, just HTML).
+
+---
+
+## Task 7: Build and final check
+
+**Objective:** Full build to verify everything compiles and bundles correctly.
+
+**Files:** None (verification only)
+
+**Step 1: Build**
+
+```bash
+npm run build
+```
+Expected: PASS. The `?raw` import for `.glsl` should be handled by Vite just like `.wgsl`.
+
+If Vite complains about `.glsl` extension, add to `vite.config.ts`:
+```ts
+export default defineConfig({
+  server: { open: true },
+  build: { target: 'esnext' },
+  assetsInclude: ['**/*.glsl'],
+})
+```
+
+**Step 2: Check dist size**
+
+```bash
+du -sh dist/
+```
+The GLSL source (~3KB raw) will be inlined as a string in the JS bundle. Acceptable overhead.
+
+---
+
+## Task 8: Manual smoke test (dev server)
+
+**Objective:** Verify the site works in both paths.
+
+**Files:** None (verification only)
+
+**Step 1: Start dev server**
+
+```bash
+npm run dev
+```
+
+**Step 2: Test WebGPU path**
+
+Open in Chrome/Edge with WebGPU enabled → should see the normal WebGPU spiral + DOM overlay.
+
+**Step 3: Test WebGL fallback path**
+
+Open in Firefox (no WebGPU) → should see the WebGL spiral + fully functional DOM overlay.
+
+Alternatively, temporarily disable WebGPU in Chrome (`chrome://flags/#enable-unsafe-webgpu` → Disabled) and reload.
+
+**Step 4: Verify DOM overlay on both paths**
+
+- Click through nav tabs (Home, About, Projects, Resume)
+- Open a project detail, click back
+- Scroll resume
+- Confirm mouse movement affects the background (cursor glow)

+
+## Summary of changes
+
+| File | Action | Lines |
+|------|--------|-------|
+| `src/engine/types.ts` | Create | ~6 |
+| `src/engine/shaders/fullscreen.glsl` | Create | ~108 |
+| `src/engine/gl-renderer.ts` | Create | ~110 |
+| `src/app.ts` | Modify: add GL fallback init | +8, ~4 changed |
+| `src/main.ts` | No changes needed | 0 |
+| `index.html` | Update fallback message text | ~2 lines changed |
+| `vite.config.ts` | Possibly add `assetsInclude` for `.glsl` | +1 line |
+
+Total: ~230 new lines, ~6 lines modified. No DOM overlay code touched. No existing shader touched.
+
+---
+
+## Risks and mitigations
+
+1. **Vite doesn't handle `.glsl` with `?raw`** — Mitigation: add `assetsInclude: ['**/*.glsl']` to vite config. Vite treats included assets as raw strings by default when imported with `?raw`.
+
+2. **GLSL precision differences** — The WGSL shader uses `f32` (IEEE 754 binary32). WebGL fragment shaders default to `mediump` which may not have enough precision for the spiral math. Mitigation: use `precision highp float;` at the top of the fragment shader. All modern mobile and desktop GPUs support `highp` in fragment shaders.
+
+3. **UBO layout mismatch** — If the GLSL compiler pads the struct differently than expected, the uniform data will be misaligned. Mitigation: explicitly use `layout(std140)` which guarantees the exact layout we've matched. The TS array layout was designed to match std140 already (d[6],d[7] = 8 bytes of padding before `date`).
+
+4. **`noUnusedLocals` / `noUnusedParameters`** — If any GL renderer methods or params trigger TS unused warnings. Mitigation: all method implementations use their params; the `_ready` naming convention is already established in the project.
+
+5. **Context loss handling** — The WebGL2 context can be lost. Mitigation: WebGL2 has `webglcontextlost` / `webglcontextrestored` events. For now, the current codebase doesn't handle WebGPU device loss recovery (beyond logging), so feature parity is sufficient. Can add recovery in a follow-up.

+# Hugo Transition Plan — WebGPU Portfolio
+
+> **For Hermes:** implement this plan via `opencode` CLI, task-by-task, small verifiable chunks wrapped with `timeout`. Verify each task (typecheck/build/hugo/curl) before moving on. After any timeout, inspect `git status` before continuing.
+
+**Created:** 2026-08-16
+**Goal:** Replace the Vite/WebGPU single-page app with a Hugo static site (hugo-coder theme, dark), keeping the WebGPU spiral visuals as a full-page homepage background behind the theme. Everything else — content, nav, routing, resume, projects, blog — becomes Hugo.
+
+---
+
+## 1. Locked decisions (recap)
+
+| # | Decision | Choice |
+|---|----------|--------|
+| 1 | Engine scope | Minimal background shader only (spiral + mouse + accent/dim). Drop text-renderer, router, DOM overlay, TS data files |
+| 2 | Engine build | Keep Vite + TS as a sub-package; emit a static JS bundle into Hugo `static/` |
+| 3 | Repo layout | In-place monorepo; Hugo at root, engine under `gpu-bg/` |
+| 4 | Homepage canvas | Full-page background, dark theme overall |
+| 5 | Identity | "Djosen" as site title + displayed author (full alias); resume keeps real name "Ahmed Mohamed" |
+| 6 | Resume | Structured `data/resume.yaml` + custom Hugo layout |
+| 7 | Projects | `categories` taxonomy (programming/hardware/visuals/music), tech → `tags` |
+| 8 | Menu + blog | Home, About, Projects, Resume, Blog — blog enabled |
+| 9 | Accent | hugo-coder default blue accent; background stays emerald (two-tone, revisit after render) |
+| 10 | baseURL | `https://djosen.one/` |
+| 11 | Theme install | git submodule at `themes/hugo-coder` |
+| 12 | Old SPA code | Archive (tag + `archive/` folder), do not delete |
+| 13 | CI/CD | Deploy workflow lives server-side; produce a handover doc to adjust it |
+

+
+## 3. Engine extraction — what survives vs. is archived
+
+**Survives into `gpu-bg/` (copied unmodified):**
+- `engine/renderer.ts` (WebGPU) — `UiState` interface lives here
+- `engine/gl-renderer.ts` (WebGL2 fallback)
+- `engine/types.ts` (`RendererLike`)
+- `engine/shaders/fullscreen.wgsl` + `fullscreen.glsl` — **shader math stays byte-identical**
+- `ui/input.ts` (pointer tracking; tiny, feeds `state.mouse`)
+
+**New file — slim bootstrap `gpu-bg/src/main.ts` (replaces app.ts + main.ts):**
+- Look up `#gpu` canvas; if absent, no-op (partial only included on homepage).
+- `init()` WebGPU → fallback WebGL2; only if both fail, hide canvas (no separate #fallback UI — Hugo content still shows).
+- `resize()` + DPR cap 2 (reuse logic from app.ts).
+- `requestAnimationFrame` loop: feed `resolution`, `time`, `mouse`, and **fixed uniforms**: `scene = 0`, `dim = 0.0`, zeroed `stemMultipliers` (32 floats).
+- No router, no overlay, no scene switching. The `scene`/`dim`/`stemMultipliers` plumbing is collapsed to constants at the bootstrap boundary — the renderer and shader remain untouched.
+
+**Archived into `archive/` (deleted from active tree):**
+- `app.ts`, `main.ts` (superseded by slim bootstrap)
+- `router.ts` (Hugo does routing)
+- `ui/overlay.ts` (Hugo renders content)
+- `data/**` (all content → Hugo; see section 4)
+- `engine/text/**` (text-renderer, text-layout, slug-generator — confirmed orphaned: only self-references, nothing imports them)
+- root `index.html`, `package.json`, `package-lock.json`, `tsconfig.json`, `vite.config.ts` (move to `archive/`; new engine gets its own under `gpu-bg/`)
+
+**Note on shaders:** the WGSL/GLSL scene-palette `if/else` chain will now always resolve to `scene0` (emerald). Do NOT simplify the shader during this transition — it risks introducing bugs in working math. Flag as an optional later cleanup.
+
+---
+
+## 4. Content migration map
+
+| Source | Destination | Notes |
+|--------|-------------|-------|
+| `pages.ts` home entry + `scenes/hero.ts` | `content/_index.md` + `params.info` | tagline → `params.info = "Creative Developer | Game Developer | Software Engineer"`; welcome body → `_index.md` |
+| `scenes/about.ts` | `content/about.md` | Convert HTML `<p>/<ul>/<li>/<a>` → Markdown. Content: aliases, TUM masters, graphics/XR/games/AI background, Forza/Turn10, Siemens AI, hobbies list, emails + discord |
+| `scenes/contact.ts` | — (drop) | It's a placeholder (`hello@example.com`); real contact lives in about + social config |
+| `scenes/projects.ts` (intro) | `content/projects/_index.md` | Keep the "not an exhaustive list…" intro text |
+| `projects/index.ts` categories | taxonomy config | `categories` = programming, hardware, visuals, music (empty ones become invisible terms until populated) |
+| `projects/radiance-caching.ts` | `content/projects/radiance-caching.md` | frontmatter below |
+| `projects/point-cloud.ts` | `content/projects/point-cloud.md` | " |
+| `projects/evol-engine.ts` | `content/projects/evol-engine.md` | " |
+| `projects/auv-simulation.ts` | `content/projects/auv-simulation.md` | " |
+| `projects/improv-gfx.ts` | `content/projects/improv-gfx.md` | " |
+| `resume.ts` | `data/resume.yaml` + `layouts/resume/single.html` | full structure preserved |
+| `scenes/resume.ts` (title/subtitle) | `content/resume.md` frontmatter | title "Resume" |
+
+**Project frontmatter shape:**
+```toml
++++
+title = "<name>"
+description = "<tagline>"
+date = "<parseable date>"          # for Hugo ordering
+period = "<human range>"            # e.g. "12/2025 — 06/2026"; source dates are ranges/years
+tags = ["<tech...>"]                # tech[] → tags
+categories = ["programming"]        # all 5 currently live in "programming"
++++
+<markdown body from content>
+```
+
+**Date handling:** source `date` values are ranges (`12/2025 — 06/2026`) or bare years (`2024`, `2021`). Hugo needs a real date for list ordering — set `date` to the range end (or a sane parseable date) and preserve the human string in a custom `period` frontmatter field, displayed by the projects list template. `tech` → `tags`, category → `categories`.
+
+**Resume name divergence (intentional):** site identity = "Djosen" (decision 5), but `data/resume.yaml` keeps `name: "Ahmed Mohamed"` — a CV must carry the real name. Flag if you want otherwise.
+
+---
+
+## 5. Theme setup (hugo-coder, dark)
+
+- `git submodule add https://github.com/luizdepra/hugo-coder themes/hugo-coder`
+- **Requires Hugo extended** (theme compiles SCSS via Hugo Pipes).
+- `config.toml` key points:
+  - `baseURL = "https://djosen.one/"`
+  - `title = "Djosen"`, `theme = "hugo-coder"`
+  - `params.author = "Djosen"`, `params.info = "<tagline>"`, `params.description`, `params.keywords`
+  - `params.colorScheme = "dark"` (pin dark; user wants dark overall)
+  - `params.avatarURL = ""` (no avatar for now — leave off; add later)
+  - `params.social`: github (`github.com/inedited`), linkedin (`linkedin.com/in/inedited/`), email (`ineditedofficial@gmail.com`)
+  - `menu.main`: Home `/`, About `/about`, Projects `/projects`, Resume `/resume`, Blog `/posts`
+
+**Custom layouts (the only real theme surgery):**
+1. `layouts/partials/gpu-background.html` — `<canvas id="gpu" aria-hidden="true"></canvas>` + `<script src="{{ "gpu/engine.js" | relURL }}" defer></script>`.
+2. `layouts/index.html` — override homepage: include the partial; canvas is `position: fixed; inset: 0; z-index: -1`; content container gets transparent/dark glass background so the spiral shows through with readable text.
+3. `static/css/custom.css` — the canvas + glass styling above; loaded via the theme's head hook (`layouts/partials/head.html` override, or hugo-coder's `custom_css` param if present — **verify exact hook during implementation**).
+4. `layouts/resume/single.html` — render `site.Data.resume` (summary, work, education, skills) matching the current card/pill visual but in hugo-coder's palette.
+5. `layouts/projects/list.html` — only if the default list doesn't show `period` + `description` + `tags` acceptably.
+
+---
+
+## 6. Build orchestration
+
+**Engine (`gpu-bg/`):** `vite build` → a single self-contained bundle (WGSL/GLSL inlined via `?raw`) emitted to `gpu-bg/dist/`, which the Hugo build copies into `static/gpu/`. Configure `vite.config.ts` build `outDir` + `assetsInlineLimit` so shaders inline; `assetsInclude: ['**/*.glsl', '**/*.wgsl']`.
+
+**Dev workflow:**
+- `cd gpu-bg && npm run build` (engine), then `hugo server` from root (watches content + the built bundle in `static/`).
+- Optional single `npm`/`Makefile` orchestration script: `build:engine && hugo server`.
+
+**Dockerfile (3-stage):**
+```dockerfile
+FROM node:22-alpine AS engine
+WORKDIR /gpu
+COPY gpu-bg/package.json gpu-bg/package-lock.json* ./
+RUN npm ci
+COPY gpu-bg/ ./

+**Critical:** the build context must contain the initialized `themes/hugo-coder` submodule. Any clone/deploy step must use `--recursive` or run `git submodule update --init --recursive` before `docker build`.
+
+**nginx.default.conf changes:** replace the SPA fallback (`try_files $uri $uri/ /index.html`) with plain static `try_files $uri $uri/ =404` (Hugo emits real `.html` per page; 404s are now legitimate). Keep security headers + gzip. Adjust immutable-cache rule to Hugo's output dirs (`/css/`, `/js/`, `/gpu/`) with fingerprint-aware caching (Hugo fingerprints via filename hash).
+
+---
+
+## 7. Task breakdown (for opencode)
+
+Each task = one opencode run, self-contained, with an explicit verify step.
+
+0. **Safety tag** — `git tag pre-hugo` at current HEAD; confirm clean tree.
+1. **Toolchain** — install/extend Hugo (extended) locally; `git submodule add` hugo-coder; init submodule.
+2. **Archive SPA** — move `src/`, `index.html`, root `package.json`/`package-lock.json`/`tsconfig.json`/`vite.config.ts` → `archive/`; update `.gitignore` (`public/`, `static/gpu/`, `resources/`, `gpu-bg/dist/`, `gpu-bg/node_modules/`).
+3. **Engine sub-package** — create `gpu-bg/` with copied renderer/gl-renderer/types/input/shaders + slim `main.ts` + `package.json`/`tsconfig.json`/`vite.config.ts`. Verify: `npm run typecheck` in `gpu-bg/`.
+4. **Engine build** — `npm run build`; verify `dist/` bundle exists and shaders are inlined.
+5. **Hugo scaffold** — `config.toml`; `content/_index.md`, `about.md`, `resume.md`, `projects/_index.md`, `posts/_index.md`; `data/resume.yaml`. Verify: `hugo` builds, homepage/about render.
+6. **Projects migration** — 5 × `content/projects/*.md` with frontmatter. Verify: `hugo` builds; `/projects` + each project URL render.
+7. **Custom layouts** — gpu-background partial, index.html override + custom.css, resume layout, projects list tweak. Verify: `hugo` builds; homepage contains `<canvas id="gpu">` + `/gpu/engine.js` link.
+8. **Docker + nginx** — rewrite Dockerfile (3-stage), update nginx.default.conf, `.gitignore`. Verify: `docker build` succeeds; `docker compose up -d`; `curl -sf http://127.0.0.1:8080/`, `/about`, `/projects`, `/resume`, `/posts`, `/gpu/engine.js` all 200; a bogus path → 404.
+9. **Docs** — write `DEPLOYMENT.md` (section 9 content) to repo; update `README.md` dev/Docker sections.
+10. **Final verification** — `npm run typecheck` + `npm run build` (engine), `hugo`, `docker compose` smoke test, and a manual browser check of WebGPU render + WebGL fallback + dark theme + canvas-behind-content.
+
+---
+
+## 8. Verification checklist (acceptance)
+
+- `hugo` build exits 0; `public/` populated with real `.html` per page (no SPA fallback).
+- Homepage renders the WebGPU spiral behind hugo-coder content; text readable (dark theme).
+- WebGL2 fallback works when WebGPU is unavailable (manual: disable WebGPU in a browser).
+- `/about`, `/projects`, `/projects/<slug>`, `/resume`, `/posts`, `/` all return 200; unknown path → 404.
+- `/gpu/engine.js` returns 200 (hashed, cacheable).
+- Resume renders from `data/resume.yaml` with real name + full work/education/skills.
+- Projects list groups under the `programming` category; tags shown.
+- Docker image builds from a recursive clone; container healthcheck passes.
+- `git status` clean of build artifacts (public/, static/gpu/, gpu-bg/dist/, node_modules/ all ignored).
+
+---
+
+## 9. DEPLOYMENT HANDOVER  (copy verbatim into repo as `DEPLOYMENT.md`)
+
+> How the site now works, and how to adjust the server-side deploy workflow (Gitea Actions + webhook) for the new build.
+
+### 9.1 How it works now (unchanged parts)
+
+Serving topology is **unchanged**. The host's system nginx (Certbot-managed TLS at `djosen.one`) still proxies `location /` → `127.0.0.1:8080`, where the Docker `web` container listens. Nothing in the system nginx (`nginx/system-default.conf` / `nginx/reverse.conf`) or Certbot setup needs to change.
+
+What changes is **what's inside the container**: instead of a Vite SPA (single `index.html` + JS), the container now serves a Hugo static site (`public/` — one real `.html` per page).
+
+### 9.2 What changed in the build
+
+- **Build chain is now two steps:** (1) `gpu-bg/` Vite build → static JS bundle, (2) `hugo --minify` → `public/`. The Dockerfile does both in stages (`node` → `hugo` extended → `nginx`).
+- **Hugo extended is required** (the theme compiles SCSS). The Docker stage uses a Hugo-extended image (pinned tag).
+- **The hugo-coder theme is a git submodule** at `themes/hugo-coder`.
+- **nginx in the container no longer does SPA fallback** — plain static serving with fingerprint-aware cache rules.
+
+### 9.3 How to adjust the server-side deploy workflow
+
+The deploy workflow (Gitea Actions `deploy.yml` / webhook script) currently clones and `docker build`s. Two adjustments are mandatory:
+
+1. **Clone with submodules.** The hugo-coder submodule must be present before `docker build`. Change the checkout step to recursive:
+   - Gitea Actions: `checkout@v3` with `submodules: recursive` (or add `git submodule update --init --recursive`).
+   - Plain webhook/script: `git clone --recursive ...` or `git pull && git submodule update --init --recursive`.
+   Without this, `hugo` fails with "theme not found" and the build breaks.
+
+2. **No other secrets/hosts change.** Registry creds, SSH/webhook target, and the `docker compose up -d` deploy command are all the same. The image just gets bigger (Hugo extended + node build layers are discarded; final nginx stage stays small).
+
+### 9.4 How to test the deployment
+
+**Local (before pushing):**
+```bash
+git submodule update --init --recursive
+cd gpu-bg && npm install && npm run build && cd ..
+hugo                                # builds public/
+docker compose build                # 3-stage build
+docker compose up -d                # maps 127.0.0.1:8080:8080
+```
+
+**Smoke test (after `up -d`):**
+```bash
+curl -sf http://127.0.0.1:8080/            | grep -q 'id="gpu"' && echo "canvas OK"
+curl -sf http://127.0.0.1:8080/gpu/engine.js -o /dev/null && echo "engine bundle OK"
+curl -sf http://127.0.0.1:8080/about/       -o /dev/null && echo "about OK"
+curl -sf http://127.0.0.1:8080/projects/    -o /dev/null && echo "projects OK"
+curl -sf http://127.0.0.1:8080/resume/      -o /dev/null && echo "resume OK"
+curl -sf http://127.0.0.1:8080/posts/       -o /dev/null && echo "posts OK"
+curl -s  http://127.0.0.1:8080/nonexistent  -o /dev/null -w "%{http_code}\n"   # expect 404
+```
+
+**Browser check (manual, WebGPU is a real-GPU feature):**
+- Homepage: spiral animates behind content; dark theme; text readable.
+- Disable WebGPU (or use a non-WebGPU browser) → WebGL2 fallback still animates.
+- No-WebGL browser → static dark page (content still readable; canvas simply doesn't render).
+
+**After deploy (remote):**
+- `curl -s https://djosen.one/health` → `ok` (system nginx health endpoint, unchanged).
+- Verify `/`, `/about/`, `/projects/`, `/resume/`, `/posts/` over HTTPS.
+- Confirm the spiral renders in a real browser (the one thing `curl` can't check).
+
+### 9.5 Rollback
+
+The previous site is preserved as the git tag `pre-hugo` and the `archive/` folder. To roll back: `git checkout pre-hugo` and redeploy with the old single-stage `Dockerfile` (also recoverable from git history). No system nginx / DNS changes were made, so rollback is purely a container-image swap.

+# Deployment Handover
+
+How the migrated Hugo site is served, and how to adjust the server-side deploy workflow (Gitea Actions + webhook) for the new two-stage build.
+
+## Serving topology (unchanged)
+
+The site is served as before. The host's system nginx (Certbot-managed TLS at `djosen.one`) proxies `location /` → `127.0.0.1:8080`, where the Docker `web` container listens. **Nothing changed** in the system nginx (`nginx/system-default.conf` / `nginx/reverse.conf`) or the Certbot/DNS setup during this migration.
+
+What changed is **what's inside the container**: instead of a Vite SPA (a single `index.html` plus JavaScript), the container now serves a Hugo static site — `public/` with one real `.html` page per path.
+
+## What changed in the build
+
+The build is now **two steps**:
+
+1. **Engine** — `gpu-bg/` Vite/Typescript build → a static JS bundle (`gpu-bg/dist/`).
+2. **Site** — `hugo --minify` → `public/`.
+
+The Dockerfile runs both in stages (`node` → `hugo` → `nginx`).
+
+Key details for the server build:
+
+- **Hugo image:** the `site` stage uses `hugomods/hugo:debian-dart-sass-go-0.165.0` — an **extended Hugo** build including dart-sass. This is required because hugo-coder compiles the theme's SCSS via Hugo Pipes (`toCSS`), and Hugo 0.129+ dropped libsass in favor of dart-sass. This replaced the deprecated `klakegg/hugo` image.
+- **Theme submodule:** hugo-coder lives as a **git submodule** at `themes/hugo-coder`.
+- **Static serving only:** the container nginx no longer does SPA fallback (`try_files ... /index.html`). It serves plain static files — each page is a real `.html`, and a 404 for a missing path is legitimate and intentional.
+
+## Mandatory server-side change (the #1 gotcha)
+
+**Your clone/checkout must initialize submodules before building.** The `themes/hugo-coder` submodule must be pulled in before `docker build`; otherwise `hugo` fails with `theme not found` and the build breaks.
+
+- **Gitea Actions `deploy.yml`:** make the checkout recursive. With `actions/checkout`, set:
+
+  ```yaml
+  - uses: actions/checkout@v3
+    with:
+      submodules: recursive
+  ```
+
+- **Plain webhook / shell:** use a recursive clone, or run the update before building:
+
+  ```bash
+  git clone --recursive ...
+  # or, on an existing clone:
+  git pull
+  git submodule update --init --recursive
+  ```
+
+Nothing else changes server-side: registry credentials, the SSH/webhook target, and the `docker compose up -d` deploy command are all the same. The image is slightly larger to build (node and Hugo-extended layers are discarded; the final nginx stage stays small).
+
+## Testing
+
+### Local (before pushing)
+
+```bash
+git submodule update --init --recursive
+cd gpu-bg && npm install && npm run build && cd ..
+hugo                                # builds public/
+docker compose build                # 3-stage build
+docker compose up -d                # maps 127.0.0.1:8080:8080
+```
+
+### Smoke test (after `up -d`)
+
+```bash
+curl -sf http://127.0.0.1:8080/            | grep -q 'id="gpu"' && echo "canvas OK"
+curl -sf http://127.0.0.1:8080/gpu/engine.js -o /dev/null && echo "engine bundle OK"
+curl -sf http://127.0.0.1:8080/about/       -o /dev/null && echo "about OK"
+curl -sf http://127.0.0.1:8080/projects/    -o /dev/null && echo "projects OK"
+curl -sf http://127.0.0.1:8080/resume/      -o /dev/null && echo "resume OK"
+curl -sf http://127.0.0.1:8080/posts/       -o /dev/null && echo "posts OK"
+curl -s  http://127.0.0.1:8080/nonexistent  -o /dev/null -w "%{http_code}\n"   # expect 404
+```
+
+### Browser check (manual — WebGPU is a real-GPU feature)
+
+- Homepage: emerald spiral animates behind the dark glass panel; text readable.
+- With WebGPU disabled, the WebGL2 fallback still animates.
+- With no WebGL at all, the page still shows its content; the canvas simply doesn't render.
+
+### After deploy (remote)
+
+- `curl -s https://djosen.one/health` → `ok` (system nginx health endpoint, unchanged).
+- Verify `/`, `/about/`, `/projects/`, `/resume/`, `/posts/` over HTTPS.
+- Confirm the spiral actually renders in a real browser — the one thing `curl` cannot check.
+
+## Rollback
+
+The previous site is preserved in the git tag `pre-hugo` and the `archive/` folder. To roll back: `git checkout pre-hugo` and redeploy with the old single-stage Dockerfile (also recoverable from git history).
+
+No system nginx or DNS changes were made in this migration, so rollback is purely a container-image swap.

+Hugo static site (hugo-coder theme, dark) with a WebGPU spiral background on the homepage.
 
 [![Build & Deploy](https://git.djosen.one/djoser/webgpu-portfolio/actions/workflows/deploy.yml/badge.svg?branch=master)](https://git.djosen.one/djoser/webgpu-portfolio/actions)
 
-Generative-art portfolio site. WebGPU canvas background, DOM overlay UI.
+## Structure
+
+- **Hugo site (repo root):** `content/` (pages, projects, posts), `data/resume.yaml`, `layouts/` (custom homepage/resume templates), `themes/hugo-coder` (git submodule), `static/gpu/` (the compiled engine bundle).
+- **`gpu-bg/`** — the WebGPU/WebGL2 background engine (`Vite` + `Typescript`), built to a static JS bundle.
+- **`archive/`** — the retired Vite SPA, preserved for reference.
 
 ## Dev
 
+**Hugo server** (site content):
+
 ```bash
-npm install
-npm run dev        # vite dev server (opens browser)
-npm run typecheck  # tsc --noEmit
-npm run build      # typecheck + vite build → dist/
-npm run preview    # serve built dist/
+hugo server
+```
+
+**Engine** (background):
+
+```bash
+cd gpu-bg && npm run dev
+```
+
+**Full loop** — build the engine, copy the bundle into the Hugo site, then serve:
+
+```bash
+cd gpu-bg && npm install && npm run build
+cp gpu-bg/dist/engine.js static/gpu/engine.js
+hugo server
 ```
 
 ## Docker
 
 ```bash
-# Build
-docker build -t webgpu-portfolio .
-
-# Run (foreground)
-docker run --rm -p 8080:80 webgpu-portfolio
-
-# Run (detached)
-docker run -d -p 8080:80 --name portfolio webgpu-portfolio
-
-# Compose
+docker compose build
 docker compose up -d
 ```
 
-Site at `http://localhost:8080`.
+Site at `http://127.0.0.1:8080`.
 
-### Smoke test
+## Deploy
 
-```bash
-docker run -d -p 8080:80 --name portfolio-test webgpu-portfolio
-curl -sSf http://localhost:8080/ > /dev/null && echo "OK"
-curl -sSf http://localhost:8080/assets/ | head -1     # should 200 (hashed JS)
-docker stop portfolio-test
-```
-
-### Image size
-
-~6 MB (nginx:alpine-slim + static dist). Multi-stage build — Node build layer is discarded.
+Server-side deployment (Gitea Actions / webhook) is documented in [DEPLOYMENT.md](DEPLOYMENT.md) — including the mandatory recursive-submodule checkout for the Hugo build.

++++
+
+My name is Ahmed Alaa Ahmed Mohamed (aka Djoser / Djosen / Inedited). I'm a passionate creative software engineer and game developer.
+
+I hold a master's degree in games engineering from TUM, with a strong background in graphics programming, real-time rendering, XR development, game development, and AI engineering.
+
+I have experience working on AAA titles (Forza Motorsport 8) with Turn10 Games, as well as indie games and other personal projects. If it involves computers and is fun, I'm in.
+
+Recently I've been getting into AI Engineering during my work at Siemens, and have developed workflows with Nvidia and Meta XR-AI for industrial operations.
+
+Besides my professional work, I do some other fun stuff:
+
+- Video games
+- Music production and sound design
+- Audio reactive visualizations
+- Shader programming
+- Sim racing
+- Hardware tinkering
+- Making more video games and whatnot
+
+You can reach me at [ineditedofficial@gmail.com](mailto:ineditedofficial@gmail.com) or [djoser@djosen.one](mailto:djoser@djosen.one) or "inedited" on discord.
+
+It's a little hard to try to dumb everything about me in one page so just reach out to me, let's have a chat!
