/* css/swap.css · THE SWAP CARD [redesign v3 · flag: new_trade_ui]
   Token-driven end to end so light and dark are both first-class. Fit-first:
   the whole card (header, both panels, rate, details, CTA) holds inside one
   viewport from 320px phones to short laptops; type and padding scale with
   clamp(), never with breakpoint cliffs. */
