- nginx: try_files adds $uri.html so /dev-doc, /simple-doc, /review-doc
resolve to the flat .html files before the SPA fallback (prod).
- vite: dev-only middleware mirrors the same rewrite so the clean URLs
work under `vite dev` too (no SPA-fallback / router warning).
- simple-doc: add hex values inline + a "Quick reference (for the
developer)" swatch grid (full palette + category colours) and type/
button/divider specs — kept layman. Cross-links now use /dev-doc.
dist/ rebuilt.
