/* pacebuddy.app — shared styling.
   Kept in one file so privacy, support and terms can't drift apart.

   Type: the Apple system stack (SF Pro on Apple devices, Segoe on Windows,
   Roboto on Android). For an app that lives in Apple's ecosystem this reads as
   more considered than a webfont — it's the same face as the App Store listing
   the visitor just came from, it renders at native hinting quality, and it
   costs no network request. */
