/* ============================================================
   INPUT VALIDATION — live warning surfaces for js/validation.js.

   Three layers:
     .val-banner   summary bar at the top of the input panel
     .val-badge    flag sitting on the offending row
     .val-cell     highlight on the specific field cell
   All colours come from the theme variables so the three themes
   (dark / light / sepia) stay consistent.
