- **Brand** (wordmark + logo): `frontend/src/assets/brand/*.svg`. Inline in `BrandWordmark` / `BrandLogo` / `BrandLockup` so fills can use `currentColor`. After editing an SVG, run `frontend/scripts/build-brand-components.mjs`.
- **Favicon:** `frontend/src/app/icon.svg` (hex fills — `currentColor` does not work in tab icons).
- **FDI tooth sources:** `frontend/src/assets/fdi/`. The chart uses inlined paths in `realisticToothAssets.ts`; regenerate with `frontend/scripts/extract-tooth-svgs.mjs`.
- **Prosthesis catalog illustrations:** source `frontend/src/assets/prosthesis-catalog/*.svg` (painted navy, not `currentColor`). Serve the same filenames from `frontend/public/prosthesis-catalog/` as `<img>` — Next cannot import these as URLs under Turbopack 16.1, and denture/veneer are too large to inline. Map codes in `prosthesisCatalogIcons.ts`. Copy into `public/` when adding a file.
- **`public/`** is only for files that must be fetched by URL (e.g. og images, prosthesis catalog icons). Do not put themeable brand/FDI SVGs there — `<img src>` cannot inherit `currentColor`.
