/* ============================================================
   assets/css/components.css — SmartSwap shared component layer
   ------------------------------------------------------------
   Extracts the recurring inline-style patterns (≈2,600 of them)
   into named, themeable, mobile-aware classes. Loaded AFTER
   main.css + theme.css so it can rely on the token variables and
   compose with existing component classes.

   Conventions
   -----------
   • Spacing utilities use PX values in their name: .mb-16 = 16px.
     The three legacy Tailwind-style names already in main.css
     (.mb-4, .mt-4, .mt-8 → 16/16/32px) are intentionally NOT
     redefined here. New code should use the px-named utilities.
   • Layout grids (.grid-2 / .grid-3 / .grid-auto) collapse to a
     single column at ≤768px automatically — no per-view media
     queries and no fragile [style*=] hooks required.
