cartolina.dev is a Jekyll documentation site for the cartolina-js library; both repos live side by side under /home/prochazka/src/cartolina/.
The Jekyll site uses a custom _data/navigation.yml for nav and example pages are under pages/examples/. Tilde-suffixed files (e.g. _config.yml~) appear throughout — these are editor backup files and are not part of the build; .gitignore was recently updated (uncommitted change as of this session).
A cartolina-js/docs/wiki directory is also mounted as an additional working directory, suggesting wiki content may be managed separately from the main docs site.
Ruby environment conflict: The system has snap Ruby 4.0 (/snap/bin/bundle) and apt Ruby 3.0 (/usr/bin/bundle3.0). The github-pages gem’s ffi dependency requires Ruby < 3.5, so snap Ruby breaks bundle install. Always use /usr/bin/bundle3.0 explicitly. Also requires ruby3.0-dev apt package for native extensions (bigdecimal, ffi, commonmarker, eventmachine). Bundle path is set locally to vendor/bundle (gitignored) to avoid needing sudo. README updated to reflect this.
examples.md ordering convention: implemented example links must come before unimplemented placeholder lines.
vendor/ must be in Jekyll’s exclude list (_config.yml): Jekyll would otherwise try to parse gem template files inside vendor/bundle as posts, failing with an invalid-date error on a .markdown.erb file. Added vendor/ to the exclude: key.
