-Once the repo is public, directories can reference these at stable raw URLs (`https://raw.githubusercontent.com/modem-dev/mcp/main/assets/...`).
+The square exports all derive from the same source mark as the monorepo favicon
+(`apps/docs/favicon.svg`), so the directory icon matches the one the docs site already serves.
+Regenerate the rasters from the SVG rather than editing them by hand:
+
+```bash
+rsvg-convert -w 400 -h 400 assets/logo-square.svg -o assets/logo-400.png
+rsvg-convert -w 64 -h 64 assets/logo-square.svg -o assets/logo-64.png
+pngquant --force --quality 65-95 --output assets/logo-64.png -- assets/logo-64.png
+```
