The logo
The mark, the lockup and the app tile are in /brand, generated by
tools/make-logo.mjs from the same geometry the site draws and the same solved palette it
ships, so they cannot drift from it. The lockup SVGs embed the latin subset of Newsreader:
an SVG that merely names a font renders as Times wherever that font is absent, and the failure is silent.
Everything else
The type is Newsreader and
Inter, both under the SIL Open Font Licence. The
icons and the mark are drawn in this repository. The palette is solved by tools/palette.mjs
and every pair is checked before it ships.
