/* Heatmap table — overrides on top of .teg-table defaults.
   Loaded only on /scoring/heatmap via extra_head.

   The table element carries both .teg-table and .heatmap-table so it inherits
   font (Roboto Mono from clean.css) and base styles from .teg-table. All
   overrides here use the double-class selector .teg-table.heatmap-table which
   has higher specificity (0,2,X) than .teg-table (0,1,X), so no !important needed.

   Cell colours: inline styles from Python (continuous gradient interpolation).
   Pills: global .pill / .pill--active / .pill-group from base-vars.css. */
