/* ──────────────────────────────────────────────────────────
   Auth Shell — shared login layout
   Flat design: no gradients, no backdrop-filter, no oversized
   rounded cards. Token-based colors, clamp() spacing.

   Collapse breakpoint: ≤960px so 1366×768 and 1280×800 laptop
   widths stay two-column, even at 125% browser zoom
   (1366 / 1.25 = 1093px, 1280 / 1.25 = 1024px — both > 960).
