/* ============================================================================
   TTM component library — the spec's Component Patterns, implemented once.
   Pure token consumers (tokens.css is the only place a color may be defined).
   Spacing doctrine: structural spacing uses the --ttm-spacing-* scale;
   intra-component optical rhythm (.3/.6/.8/1.1rem …) is deliberate taste
   and stays literal — never introduce a new color or font literal though.
   Consumed by every surface: map chrome widgets (menu, gate, toasts, footer),
   dashboard primitives (card, kv, bar, badge, meter, table), and form
   components (buttons, input, select, switch, color, range).
