/* ==========================================================================
   AI API Gateway — user panel, refinement layer
   Loaded last (priority 999) so it can unify the look of every tab.

   What this layer does, in order:
   1. Shell     – flat canvas, quiet header, sidebar with an inline-start marker
   2. Headers   – one consistent page header for every tab
   3. Surfaces  – one card recipe: hairline border, single radius, no gradients
   4. Tables    – light header, roomy rows, tabular numbers, hover state
   5. Controls  – 38px inputs/buttons, visible keyboard focus
   6. Mobile    – bottom navigation, edge-to-edge cards, key table as cards
   7. Motion    – only what answers a tap; respects reduced-motion
   It only reads the existing --aiapi-* tokens, so light/dark mode and the
   colour presets from the Theme Settings drawer keep working unchanged.
