## Code integration
- `src/lib/site.ts`: BRAND_ASSETS paths -> final brand PNG assets

- `src/styles/global.css`: header brand mark path updated to `/assets/brand/logo-mark.png`

## Regression contract checks
- Anchors core unchanged: `#a-propos`, `#projets`, `#contact`
- Tracking contract untouched (events/params)
- SEO public resources preserved (`robots.txt`, `sitemap.xml`, canonical/OG/Twitter)

## Build checks
- `npm run typecheck`: PASS (0 errors)
- `npm run build`: PASS

## Notes
- SVG outputs are derived wrappers from PNG source (no native vector source available).
- Fallback behavior maintained: display relies on PNG quality; SVG kept for compatibility.
