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 the v5 sober mobile-first layout: a neutral white surface (the category is a label in the meta row — no more per-category pastel card backgrounds; colour is reserved for actions/status), the description as the primary line (2-line clamp), the repo name as a small monospace secondary line, a colour-coded AA status chip (dark text on a light tint; frozen/duplicate get a muted slate pastille instead of card-level opacity) and verbatim GitHub topic pastilles (area-* omitted), and a 44px-tap-target links footer: Stable (solid accent, only when the repo has a v* tag; points at the canonical stable/ pointer path) BEFORE Latest (the develop render), Source (public repos only) and a Branches native <details> disclosure of the non-default branches (each linking a previews/<branch>/ path; works with JS blocked). Filters: sticky slim header with live search; the filter panel collapses behind a "Filtres" toggle below lg and is inline from lg up; a category segmented control (aria-pressed), a topic checkbox dropdown (AND semantics) and a result count; last-update dates render as absolute short French dates at build time, rewritten to "il y a X" by JS when available. Plain vanilla JS.

• Live: https://bruno.univ-tln.fr/teaching-material/catalog/ — regenerated every 6 hours via GitHub Actions (.github/workflows/catalog.yml: build job on hosted ubuntu-latest (Python 3.12 + Node 22) runs python catalog.py and then builds the purged CSS; deploy job on a self-hosted ebpro-org runner rsyncs public/ (--delete scoped to catalog/) to the teaching server (vai.univ-tln.fr, served under bruno.univ-tln.fr/teaching-material/) and drops a root redirect index.html), plus on-demand via workflow_dispatch. The generated public/ is not committed.
• Architecture (v5.1): a pure Python 3 stdlib generator (no third-party deps) emits a static public/index.html; styling is a build-time purged Tailwind v3.4.19 stylesheet — tailwind.config.js + inputs.css → public/app.css via the CI step npx tailwindcss@3.4.19 -c tailwind.config.js -i inputs.css -o public/app.css --minify, whose single content source is catalog.py itself (every class literal lives in its HTML templates). No runtime CDN and no webfont requests: the page links only its local stylesheet and uses the system font stack. daisyUI was removed in v5 (its pre-built full.min.css cannot be purged and its CDN delivery was a blocklist/FOUC risk); the card/chip/button/ disclosure components are hand-rolled in inputs.css on top of the default Tailwind palette (slate surfaces, single indigo accent), light-only (darkMode: "class"), with visible keyboard focus, a skip link and prefers-reduced-motion support. Locally: GITHUB_TOKEN=… python catalog.py regenerates index.html; run the npx command above to regenerate app.css.
• Fleet freshness: whenever a course site finishes rendering, the shared _quarto-utils reusable workflow (render-quarto.yml) runs its trigger-catalog job, which dispatches a catalog.yml rebuild of this repo on main (needs CATALOG_DISPATCH_TOKEN with Actions:write here; warn-only — the 6 h cron is the fallback).
• The cleanup subcommand (python catalog.py cleanup [--dry-run] [--keep N]) prunes old Cloudflare Pages preview deployments (needs CF_API_TOKEN) and is driven by .github/workflows/cleanup.yml (weekly, Sunday 04:00 UTC).
• 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.
