/* ==========================================================================
   TAT YO GRANDMA — SHARED COMPONENT LIBRARY
   Phase 4. Implements Phase 3 §4–§9 component rules exactly.
   --------------------------------------------------------------------------
   NAMING: BEM-ish. Blocks are the component root (.btn, .card, .lb …).
   Elements use __ (e.g. .card__body). Modifiers use -- (e.g. .card--dark).
   Variants use a single hyphen (e.g. .btn-outline, .card-b).
   Theme context (dark base vs paper inversion) is set by a section-level
   .on-paper class or by the component's own modifier — components do not
   guess the surface they sit on.
   --------------------------------------------------------------------------
   SURFACE RULES:
   - --muted is DARK-SURFACES ONLY. On light surfaces use --ink-60/--ink-40.
   - --accent never carries small white text — fills use --accent-deep.
