/* ─────────────────────────────────────────────────────────────────────────────
   XYTRO CLOUD — the same design language as the Xena webchat.

   WHAT THIS REPLACES
   ------------------
   The page was glass-and-gradient: two radial washes, blurred panels at 72% opacity,
   20px radii, a gradient wordmark, a gradient "plan" chip and a gradient primary button.
   Every element competed, so nothing led — the file grid is the subject of this page and
   it was the quietest thing on it.

   THE RULES USED HERE (identical to the webchat overhaul)
   ------------------------------------------------------
   1. ONE accent. Teal marks the primary action and the selected item, nothing else.
      Anything that used the gradient for decoration now uses ink or a hairline.
   2. Neutral, solid surfaces. Panels are a flat token, not a blur; separation comes from
      a 1px line and a 1px shadow, not from opacity games that break over any background.
   3. One type scale — .72 / .78 / .86 / 1.02 / 1.28rem — and ONE family. Mono is for
      numbers only (sizes, percentages, the clock), because that is where it earns its
      place by lining digits up.
   4. Tighter radii (14 / 10 / pill). 20px on a 42px tile reads as a blob.
   5. Dark and light are the SAME design with the tokens swapped: the light block at the
      end only redefines colours, so nothing can drift out of sync.
   6. The file grid leads: quiet cards, one clear hover, and the size as the only
      secondary line. Actions stay in the toolbar so the grid has no chrome of its own.
