   Wink — design system  ·  "Twilight Glass"
   --------------------------------------------------------------------------
   POV: deep dusk sky (navy → violet) · a single warm gradient crescent moon ·
   frosted glass cards floating over a soft mountain horizon · big, light
   numerals · pastel-rainbow accents used sparingly. Calm, premium, classy.

   Design law: one primary action per screen · no shame, ever (a bad night is
   data, never a failure) · the medicine (your sleep window) is always the
   loudest thing · comfort features are clearly labelled as comfort, not cure ·
   big tap targets · gentle motion · respects prefers-reduced-motion.
