/* SaraHome — 通用對話窗 (`.modal` markup + `js/modal.js`) 皮膚 (v1.13, 2026-10-15)
 *
 * 根因: 呢套皮膚原本喺 `pages/account.css` 同 `pages/agent-new-listing.css` 各寫一份
 * (兩份數值已經漂: z-index 100 vs 1000、radius 12 vs 16、overflow auto vs flex column)。
 * 結果 `super_admin/audit_log` 用同一個 markup 但兩份 CSS 都冇載入 → `.modal` 冇任何
 * position/backdrop 規則, 開窗時變成**內嵌喺頁面流內**的一塊 (無遮罩、唔置中),
 * 「點窗以外關閉」亦無從谈起 (§R-N+416 單一來源守則: 同一 selector 嘅 layout 屬性只准一處定義)。
 *
 * 而家: 呢檔 = `.modal` 系列嘅唯一來源 (base.html `_CSS_CHAIN` 核心層載入, 全站可用);
 * 頁面部 CSS 只准保留自己專屬嘅變體 (例 `.modal-card-danger` 嘅紅色 header),
 * 唔准再對 `.modal` / `.modal-card` / `.modal-body` 落 position / max-width / overflow。
 * 對位 §R-N+372.13 (純 CSS 化) + §R-N+78.7 (base.html 用 v=timestamp cache-bust)。
