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

+Researched and implemented a real-time radiance cache for volumetric path tracing using 3D Gaussian Splatting and a fused MLP as the cache representation.
+
+Developed an online differentiable optimization pipeline in CUDA that adapts the Gaussian cache to dynamic lighting and transfer function changes during rendering.
+
+Built a spatial-hash-based fused MLP for radiance caching on volumetric heterogeneous media. Supervised by Prof. Westermann.
