/* ── Cover patterns (#793 follow-up) ───────────────────────────────────────
   A flat two-stop gradient reads as "no cover chosen" rather than as art. These
   layer texture OVER the identity gradient, so the tile looks designed while the
   HUE still comes from WatchListPalette.SlotFor — a list keeps the same colour on
   its card, its detail header and its picker dot, which is the whole point of #793.
   The user picks the PATTERN; the palette still owns the colour.

   Pure CSS on purpose: no image assets to license, host, cache or ship, nothing
   for the server to fetch, and a few hundred bytes instead of megabytes. They
   inherit #790's theme-invariance for the same reason the gradients do — this is
   cover art, and cover art does not dim in dark mode.

   ⚠ The texture MUST go on a pseudo-element, never on background-image of the
   same element. .wlc-grad-N sets the `background` SHORTHAND, so any later
   background-image on that element REPLACES the gradient instead of stacking —
   which renders the tiles grey with no hue at all. Measured, not theorised.

   Every layer is white/black alpha only, so ONE definition works over all five
   hues instead of five variants each. */
