Separate framework source from website:
- src/layers/ + src/main.css: CSS framework source (was assets/css/)
- site/: Hugo website (content/, layouts/, hugo.toml)
- dist/: built output (asw.css, asw.min.css)
- vendor/open-props/: vendored dependency with version tracking
- Hugo module mounts: dist/ → static, site runs from site/
Build: hugo --source site/ passes (105 pages).
npm run build produces dist/asw.css.

Distinct from articles/essays/notes — pages have no publish lifecycle,
no date, no TOC, no prev/next. <main> landmark, not <article>.
Groundwork: layouts/page/single.html + content/pages/about.md stub.
