        the expand/collapse itself; keyboard + screen-reader open state

     2. `.ex-cards` — stacked cards, one per exercise (pattern "A", Erik's
        pick for user_exercises.php).
   history.php intentionally NOT touched here — folded into B-17's overhaul

   browser's default `[hidden] { display: none }` (author stylesheet rules take
   precedence over user-agent rules regardless of specificity), so JS toggling
   `row.hidden = true` had no visual effect: every major row stayed visible
