/*
 * Bulk Play Copy (#303)
 * ---------------------
 * Styles for the bulk-copy mode toggle, sticky action bar, per-card selection
 * checkboxes, selected-card highlight, master-view representative hint, and the
 * confirm modal. Lifted from the designer mockups
 * (docs/mockups/2026-09-21-issue-303-bulk-play-copy/src/_shared.css, the
 * ">>> NEW COMPONENT <<<" blocks) and adapted to the real DOM produced by
 * app/views/shared/_bulk_copy_controls.html.erb + app/javascript/bulk_copy.js.
 *
 * Design rules honoured:
 *   - Amber --primary is the ONLY selection accent (never offense/defence).
 *   - All values come from variables.css / existing components — no new tokens.
 *   - Selected card uses NO transform → zero layout shift.
 *   - Multi-cue selection (ring + wash + filled box + corner tick).
 *
 * NOTE ON LOAD ORDER: this file MUST be loaded AFTER forms_dark.css in the layout,
 * because forms_dark.css applies `!important` to every <input>/<select>. The
 * rules below use matching-or-higher specificity plus !important where needed so
 * the custom checkbox / toggle / select styling wins.

   the .btn-primary amber rule. We win via the existing element IDs (specificity
   1,x,y), which dominate regardless of theme since the tokens swap themselves. */
