   Onioncore tokens lifted directly from ../DESIGN.md. The coloring

/* ----- 0. Fonts (SELF-HOSTED — do not put these back on a CDN) -----
   Vendored locally rather than loaded from fonts.googleapis.com. Two
   reasons, both load-bearing for this particular product:

     1. Offline. The app's whole promise is that it works with no
        network. A CDN font means the logo and every label silently
        fall back to system fonts the moment the kid is off-grid —
        and with Bungee and Press Start 2P that isn't graceful
        degradation, it's a different-looking app.

     2. Data Safety. Tiny Canvas declares "no data collected" and
        deliberately ships no analytics (see the GoatCounter note in
        index.html). A Google Fonts request hands Google the client IP
        on every single launch, contradicting exactly that claim — and
        it is the sort of thing a Designed for Families review looks
        for.

   All three are SIL Open Font License, free to self-host.
