# Font provenance

The WOFF2 binaries were copied from the repository's installed Fontsource
packages and are intentionally limited to the Latin subset needed by the brand
system. The TTF binaries are unmodified full-font files from the official
Instrument repositories and serve as deterministic inputs for outlined logo
geometry. SHA-256 values identify every distributed file and its exact source.
