# brand/fonts: licenses

All three families are open-licensed under the **SIL Open Font License 1.1 (OFL-1.1)**. The full texts are in `licenses/`. None of them declares a Reserved Font Name.

- **Source:** the npm registry, `@fontsource` / `@fontsource-variable` 5.3.0, Latin subset (fetched with `npm pack` on 2026-09-27).
- **The `.woff2` files** are the Fontsource files, unmodified. The site build copies every `brand/fonts/*.woff2` to `/brand/fonts/`.
- **The `.ttf` files** are lossless woff2-to-TTF conversions of the same files, made with fontTools (flavor removed, no other change). `build_brand.py` reads them to outline logos and captions; they also suit tools that don't read woff2.

`brand/fonts.css` declares the `@font-face` rules with these family names; the paths in it are relative to `brand/`.

The logo instance used by `build_brand.py`, made in memory and never saved, is Fraunces wght 900 / SOFT 100 / WONK 0 / opsz 144. Italic captions use WONK 1.

Notes
- The OFL allows these files to be used, embedded, converted and redistributed with their license, but they must not be sold on their own. Logos and captions exported as vector outlines are artwork, not Font Software.
- MOTION's Archivo, Inter and JetBrains Mono were removed from `brand/fonts/`; nothing in the new brand uses them. The review sheets in `brand/directions/` (the archive) keep their own copy of Inter and JetBrains Mono in `brand/directions/fonts/chrome/`.
