Bastien Chanot 86d4c729ed docs(memory): capitalize BDR-005 favicon strategy + LRN-002 PIL icon recipe 
- BDR-005: SVG primary + PIL-generated PNG/ICO fallback for favicon set;
  alternatives (rsvg-convert/inkscape, SVG-only, online generator) rejected
  with reasons; CV mirror deferred to user finalization.
- LRN-002: PIL supersample x8 + Lanczos downscale produces clean
  small-format icon antialiasing without rsvg-convert/inkscape/ImageMagick.
- journal: 2026-05-17 entry — extended-vitrine refactor (1369d27) +
  favicon set (ef31fb3); CV files left untouched (user WIP).

BDR-001 — Static single-file site, no framework

  • Date: 2026-05-15
  • Statut: accepted
  • Décision: index.html unique, CSS inline <style>, JS vanilla inline <script>. Aucun bundler, aucun build step.
  • Pourquoi: Landing perso 1 page. Audience recruteurs/CTO. Critère "click Contacter <10s". Zéro dep, zéro maintenance, zéro tracking. Indexable par défaut.
  • Alternatives rejetées:
    • Astro — overkill, ajoute build step pour 1 page.
    • React SPA — interdit pour site public indexable (cf ~/.claude/CLAUDE.md).
    • HTML + CSS externes — éclate 1 livrable en 3 fichiers sans bénéfice.
  • Référence: index.html, section Stack de CLAUDE.md.

BDR-002 — weasyprint pour génération PDF CV

  • Date: 2026-05-15
  • Statut: accepted
  • Décision: weasyprint CV_Bastien_Chanot.html CV_Bastien_Chanot.pdf à chaque modif HTML CV.
  • Pourquoi: weasyprint déjà installé (~/.local/bin/weasyprint). Chromium absent. wkhtmltopdf déprécié.
  • Alternatives rejetées:
    • Chromium --print-to-pdf — pas installé.
    • wkhtmltopdf — déprécié + WebKit ancien, rendu moins fidèle.
    • Print manuel via navigateur — pas reproductible, dérive entre HTML et PDF.
  • Warnings connus: box-shadow: none ignoré par weasyprint, sans impact visuel.
  • Référence: CV_Bastien_Chanot.pdf.

BDR-003 — Position pro: CDI prioritaire, missions freelance en parallèle

  • Date: 2026-05-15
  • Statut: accepted
  • Décision: Site annonce CDI systèmes/embarqué prioritaire, ZenQuality (freelance) en parallèle. Géo: full remote idéal, hybride 1-2 j/mois si Paris, mobilité Pays de la Loire.
  • Pourquoi: Recadrage user. Première version annonçait "Missions long terme & expertise" — pas représentatif. Hiérarchie CDI > freelance maintenant explicite (hero eyebrow + about para + callout + CV header).
  • Référence: index.html (hero-eyebrow, about-text para 3, about-callout) + CV_Bastien_Chanot.html (header).

BDR-004 — Containerize site with nginx:alpine behind reverse proxy

  • Date: 2026-05-15
  • Status: accepted
  • Decision: Ship site as bchanot-web Docker container (nginx:1.27-alpine). Container listens on port 80 internally; host port configurable via PORT env (default 8080), bound to 127.0.0.1. Host nginx terminates TLS + proxy_pass to container.
  • Why: VPS hosts multiple sites (zenquality.fr, nuit-folle.zenquality.fr, bchanot.fr). Container isolates static assets + nginx config, easier rollback, reproducible build. Loopback bind blocks direct external hits, forces traffic through host nginx (TLS, rate limit, logs).
  • Hardening: read_only: true, cap_drop: ALL + minimal cap_add, no-new-privileges, tmpfs for /var/cache/nginx + /var/run + /tmp. CSP allows inline CSS/JS (project convention) + Google Fonts. HSTS deliberately omitted at container level — set by outer proxy after TLS termination.
  • Alternatives rejected:
    • Bare static files served by host nginx — no isolation, config drift between sites, harder rollback.
    • Caddy / Traefik container — overkill for 1 static site, host nginx already handles TLS for other domains.
  • Reference: Dockerfile, nginx.conf, docker-compose.yml, .env.example.

BDR-005 — Favicon: SVG primary + PIL raster fallback

  • Date: 2026-05-17
  • Status: accepted
  • Decision: Ship favicon.svg (vector primary) + PIL-generated favicon-32.png, favicon.ico (16/24/32/48), apple-touch-icon.png (180×180). 4 <link> tags in <head> of index.html.
  • Why: Modern browsers fetch SVG (sharp any DPI). Legacy + iOS fall back ICO/PNG. PIL preinstalled on host → zero new dep. Mark replicates .brand::before pulse-dot (visual continuity with nav).
  • Alternatives rejected:
    • rsvg-convert / inkscape for SVG→PNG — not installed on host, setup friction.
    • SVG-only — drops Safari <14 + iOS home-screen.
    • Online favicon generator — external dep, opaque rendering, no source control.
  • CV HTML: not modified (user's WIP M state). Browser auto-fetches /favicon.ico from root → CV tab still shows icon. Link block mirror logged in .claude/tasks/TODO.md for later.
  • Reference: favicon.svg, favicon-32.png, favicon.ico, apple-touch-icon.png, index.html head, commit ef31fb3.
