docs(memory): capitalize BDR-005 favicon strategy + LRN-002 PIL icon recipe

Browse Source 
- 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-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`.

- Landing extended-vitrine refactor shipped (commit `1369d27`): meta/title sync CV, hero subtitle "Systèmes · Embarqué · Backend", stack 6→8 cards (drop VMware/Gitflow/Agile, add cgroups/namespaces/SELinux/GitHub Actions + Cloud-Infra + IA-Outils, Familier avec C++), Parcours 3 entries rewritten bullets+stack pills (lone-wolf wording purged, Deewee dates corrected fév→nov 2017), new Projets section (Git auto-hébergé + Homelab), new Méthode section (5 points), contact email → bastien@bchanot.fr.
- Favicon set added (commit `ef31fb3`): SVG primary + PIL-generated PNG/ICO/apple-touch. Brand pulse-dot translated to icon. BDR-005 + LRN-002 logged.
- CV files (`CV_Bastien_Chanot.html`, `.pdf`) untouched — user's WIP M state, off-scope per brief.

## LRN-002 — PIL supersample ×8 + Lanczos = clean small-format icon antialiasing
- **Date**: 2026-05-17
- **Pattern**: Render icon at 8× target size via `ImageDraw.rounded_rectangle` + `ellipse` on RGBA canvas, then `Image.resize((target, target), Image.LANCZOS)`. Output rivals `rsvg-convert` / `inkscape` for simple geometric shapes. Crisp at 16×16 favicon scale, no visible jaggies.
- **Context**: Generated `favicon-32.png`, `apple-touch-icon.png` (180×180), `favicon.ico` (multi-size 16/24/32/48) for `bchanot.fr` from scratch — no `rsvg-convert` / `inkscape` / `ImageMagick` on host. Single PIL script, ~20 lines.
- **Future application**: Any project needing a PNG/ICO icon set with a stdlib-only Python toolchain. Skip if shape is complex (text rendering, gradients, curves) — use `rsvg-convert` or commit a finalized PNG instead.
