The public front page of Open Platform (www.open-platform.sh), as a forge app: one Bun server, no
dependencies, no build step. The page is copied from the former site; the sign-in and console that
used to live there are retired and answer with a plain page that points to the forge.
static/ holds the page, its stylesheet, the architecture diagrams and the share image.
src/server.ts serves them, plus /robots.txt and /sitemap.xml.
SITE (default https://www.open-platform.sh) is the address used in canonical and share tags.
Old paths: /index.html redirects to /; /console answers 410 with a page; /api/auth/*
redirect to /console; other /api/* answer 410 JSON.
