## Fonts
No font binaries are bundled. The daemon receives one to four font file paths
on its command line and tries them in that order; it does not discover fonts by
family name or directory contents. `font/PROVENANCE` retains the exact
checksums, source revisions, and license records for the three Noto faces that
were formerly stored in the repository.
on its command line, validates them, and registers them as Pango application
fonts. Pango shapes each complete string and selects glyph fallback from the
registered fonts and the normal system font set. Exact command-line file order
is deliberately not promised: preserving it would require a separate
Fontconfig policy alongside Pango's fallback. `font/PROVENANCE` retains the
exact checksums, source revisions, and license records for the three Noto faces
that were formerly stored in the repository.
The Docker renderer tests obtain their fonts from signed Arch packages rather
