/* ═══════════════════════════════════════════════════════════
   tw-utilities.css — Tailwind-compatible utility classes
   Offline, no-build subset that maps to the shadcn design tokens
   (single source of truth in style.css :root). Same class names as
   Tailwind so templates can use `class="flex items-center gap-2 p-4
   rounded-md bg-card text-muted-foreground"`. Unlayered on purpose so
   utilities win over the component @layer (Tailwind's utility priority).
   Spacing follows the 4/8px scale (1=4px · 2=8px · 3=12px · 4=16px …).
