Ilker ManapandClaude Opus 5.5
e751c89937
The website was a file built by hand outside the repository. It is now a template in internal/web: every gateway serves it at /about, without a key, linked from the landing page's footer, and the published site is rendered from the same template. The fonts are vendored (Latin subsets, OFL) so the page sends nobody's browser to Google. The proxy configurations it shows are copies of deploy/proxy, kept equal by a test. A development build says so instead of linking to release files that do not exist. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
