/* Statistics — the quality tab ("Jakość danych"): rules no other tab uses.

   The colours come from the approved mockups. Their hexadecimal values live in the token blocks
   below (one per theme, like `css/stats.css`); the rules use the tokens. The three accent colours
   the app already defines (`--warn`, `--accent`, `--success`) are used by name, not repeated here. */
