claude-timemachine aa36b2905a initial: zero-trust markdown tutorials site
Single-binary Go service that renders markdown pages from a runtime
volume mount. Targeted at public, no-auth, no-WAF deployment behind a
TLS ingress; security posture is defense-in-depth at every layer:

- goldmark with no WithUnsafe — raw HTML in author markdown is stripped
- CSP without 'unsafe-inline', plus HSTS, COOP, CORP, Permissions-Policy
- static handler rejects non-GET/HEAD, directory listings, dotfiles, traversal
- content loader rejects symlinks that escape the content root, dotfiles,
  and .md files larger than 1 MiB
- per-page template trees (cloned from layout) so define-blocks don't
  collide between home/category/page
- SIGHUP triggers atomic library swap — live edits on volume, no rebuild

Locale layout content/<locale>/<category>/<slug>.md. Categories without
_index.md still appear on the home page with a humanized name. Search is
a ~70-line vanilla JS scan over /search.json?lang=<locale>; swap for a
real indexer if the corpus ever balloons.
