/*
  Shared styles for the Squared Away and Dosewise web apps. Each app sets its own --brand colors.
  Design follows Apple's interface guidelines, translated for the web:
  - Type: the system font, with tracking and leading tuned per size (tight on large, open on small).
  - Response: buttons react on press (:active), instantly; never only on release.
  - Materials: chrome is translucent so content reads underneath; dialogs dim what's behind them.
  - Motion: things grow from what opened them and leave the same way, on a critically damped curve.
  - Respects reduce motion, reduce transparency, and increase contrast.
