   fk-theme.css

   All pages share this dark theme. Do NOT add per-page body/card/input/modal
   CSS duplicates — every component is defined here exactly once.

   COLOUR PALETTE (CSS custom properties)
   ───────────────────────────────────────
   --fk-bg-page    #0f1117   Page / body background
   --fk-bg-card    #161b22   Card, panel, modal background
   --fk-bg-input   #1c2128   Input, select, textarea background
   --fk-border     rgba(255,255,255,0.08)   Card / table borders
   --fk-border-in  rgba(255,255,255,0.15)   Input / select borders
   --fk-border-fo  rgba(255,255,255,0.40)   Focused input border
   --fk-text       #e6e6e6   Primary text
   --fk-muted-val  rgba(255,255,255,0.50)   Muted / secondary text
   --fk-ok         #4caf50   Success / green
   --fk-warn       #ffb74d   Warning / amber
   --fk-bad        #ff6b6b   Danger / red

   CLASS NAMING CONVENTION
   ───────────────────────
   All new classes use the fk- prefix.
   Legacy taa-* classes are aliased here for backward compatibility.
   Never add new taa-* classes; use fk-* equivalents.

   fk-card          Dark card container
   fk-card-header   Transparent card header with subtle bottom border
   fk-muted         Muted text (alias: taa-muted)
   fk-table         Unified dark table (alias: taa-table)
   fk-modal         Dark modal content  (alias: taa-modal)
   fk-ok/warn/bad   Semantic colour helpers (alias: taa-ok/warn/bad)
   fk-stat-card-*   Stat / KPI cards for dashboard use

   TABLE SORTING
   ─────────────
   Add data-sortable to <th> elements that should be click-sortable.
   fk-table.js handles click-to-sort automatically.
   Add data-sort-type="number" or "date" for non-text columns.
   Add a <input data-fk-search="tableId"> for live client-side search.
