/* ============================================================
 * admin.css — Admin Console shared component layer (Enterprise calm)
 * Session 652. Wire ở head.php SAU style.css (override author-shell shared rules).
 *
 * Scope = `body.admin-shell-mode` (ancestor của .admin-app):
 *   - Phủ cả content trong .admin-app LẪN modal/toast body-level (alertify/.zy-modal-overlay).
 *   - Isolate author (author = body.author-shell-mode) → KHÔNG regress author.
 *   - Specificity (0,2,0) > bare `.pt`/`.kpi` dupe (0,1,0) → safety margin chống silent regression.
 *     LƯU Ý: id-scoped page rule `#admin_x .pt` (1,1,0) vẫn thắng → page chỉ giữ LAYOUT/responsive,
 *     XÓA hết visual dupe (KHÔNG để "shared + dupe" cùng tồn tại → source-order ra kết quả giả).
 *
 * Token: hardcode hex cũ (#1f2a55/#0f1530/#131a36/#8b95c2) → `--ad-*` alias (map sang au-token + semantic).
 * Enterprise calm: tím chỉ primary + active; phẳng (bỏ gradient/glow); semantic score/status; scale chặt.
