/* =========================================================================
   personal — an AI calendar
   -------------------------------------------------------------------------
   Visual system notes:
   - Chrome is translucent material with content scrolling *under* it, never
     opaque bars that eat a fixed strip of the viewport.
   - Tracking is size-specific. Large text gets negative tracking (letters read
     too far apart as they grow), body sits near zero, small caps-y labels get
     positive. A single letter-spacing value is always wrong somewhere.
   - Spacing is in rem so the layout scales with the user's text size.
   - No transitions on anything gesture-driven — those are springs in JS.
     Transitions here are only for discrete state (hover, press, theme).
