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

+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`.

-### 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.
