ebpro teaching catalog

Auto-generated card-grid catalog of the ebpro teaching surface, organised in three categories only, assigned by repo name prefix: lecture- → Lecture, notebook- → Notebook, sample- → Samples (plus the forced names ConflictBot, HelloGit). Archived repos, repos carrying the status-legacy topic and non-matching names are excluded. Cards use a distinct pastel background per category (the colour is the category signal; badges show the raw GitHub topics verbatim), the description as the primary line and the repo name as a monospace secondary line, and a daisyUI button footer: Site · Develop, Site · Stable (only when the repo has a v* tag; points at the canonical stable/ pointer path), Source (public repos only) and a ⎇ Branches ▾ hover dropdown of the non-default branches (each linking a previews/<branch>/ path). Filters: a category join-group plus a collapsible topic multi-select (AND semantics), plain vanilla JS.

• Live: https://bruno.univ-tln.fr/teaching-material/catalog/ — regenerated every 6 hours via GitHub Actions (.github/workflows/catalog.yml: build on hosted ubuntu-latest, deploy job rsyncs public/ to the teaching server), plus on-demand via workflow_dispatch.
• Pure Python 3 stdlib, no third-party deps. Tailwind CSS is loaded from the Play CDN and daisyUI 4 from a pinned cssdelivr stylesheet (v1; swap to build-time compiled CSS later). The generated public/ is not committed.
• The cleanup subcommand (python catalog.py cleanup [--dry-run] [--keep N]) prunes old Cloudflare Pages preview deployments and is driven by .github/workflows/cleanup.yml.
• To change which repos are listed, adjust the category rules (CATEGORIES / FORCED_SAMPLES / _classify) at the top of catalog.py. Category assignment is by name prefix on purpose (robust to topic-labelling drift); status-legacy and archived remain topic/flag-driven.
