   Signature: a glowing constellation motif ties the whole app together — the
   same "stars connecting into light" idea used for the progress map is echoed
   in confetti bursts, idle-hint pulses, and card transitions.
   Type: no external webfonts (keeps the app 100% offline/zero-network) — a
   heavy-weight system rounded-font stack carries the friendly personality instead.
