index.html is the template; site/locales/*.json supplies all 21 application languages. Run sh scripts/assemble-site.sh after the web build, then python3 scripts/generate-star-history.py --output-dir dist for the charts. Run python3 scripts/test_site.py to check translations, links, metadata and language selection.

The root page follows the browser language, falling back to English. Language links use explicit locale paths and remember manual choices when browser storage is available. Arabic uses a right-to-left layout. The favicon uses the centered OCS lettering from assets/logo.svg, without details that disappear at small sizes. Export favicon.svg to PNG at 96, 180, 192 and 512 pixels and ICO at 16, 32, 48, 96 and 256 pixels when it changes. Favicon URLs stay fixed for search engine crawlers.

workspace.png and modeling.png are shared by the website and all README languages. The drawing screenshot also supplies the social preview; website image URLs change with their contents.

GitHub Pages runs on release publication, a call from the weekly release workflow, or a manual run. Commits and pushes do not start workflows. Deployments use website files from main and build the app from the release, recording both sources separately. Manual runs can select build_main to publish a web hotfix; see docs/releases.md.
