/* Dashboard-Learning review tab. Standalone, namespaced `dl-*`; uses the app's theme
   tokens (every palette, light/dark), the shared radius scale and the card / label /
   button / table vocabulary surface.css defines. Responsive at 760px. Mirrors the
   relationships.css conventions.

   The architecture is the shared one: a tinted ground with discrete cards floating on
   it. The control surface and every suggested edit are separate objects with a gap
   between them, never a continuous hairline-divided sheet — a hairline appears only
   INSIDE a card, joining an edit's head to its expanded body, or ruling the rows of the
   weight table. Labels are tracked mono capitals, weights are mono and tabular. */

/* The view's top padding now comes from `.view` in surface.css, which is what floats the
   first card clear of the sticky header; the old `padding: 0` here predates that rule and
   only fought it. The stack is a flex column, so hiding a block cannot leave its margin
   behind — every gap belongs to the container, not to the children. */
