/* ==========================================================================
   Sleeve — design tokens
   A quiet, warm "liner notes" aesthetic: charcoal sleeves, brass foil accents,
   one sans (Inter) throughout — headlines and body share the same typeface.

   Accessibility notes (read before editing):
   - Dimensions that relate to layout/reading are in rem, not px, so the
     whole shell reflows correctly when a person increases their browser's
     text size (WCAG 1.4.4 Resize Text / 1.4.10 Reflow).
   - No text is truncated with ellipsis anywhere; long titles wrap instead
     (overflow-wrap: anywhere) so nothing is ever hidden from view.
   - Interactive controls keep a ~2.75rem (44px) minimum hit target.
   - Focus rings are always visible; nothing relies on :hover alone.
   ========================================================================== */
