/* ═══════════════════════════════════════════════════════════════════════════
   notifprefs.css — Notification settings modal (Run 36, feature C).
   Companion of notifprefs.js. Every colour is one of admin.css's tokens; the
   overlay/content/header/close rules are admin.css's own (.modal-overlay,
   .modal-content, .detail-header, .modal-close) — this file only adds what the
   generic modal lacks: a left-aligned, scrollable body, group headings, the
   switches, and the two notes.
   ═══════════════════════════════════════════════════════════════════════════ */

/* Anchored to a fixed TOP offset, not centred like admin.css's .modal-overlay:
   the body renders a beat after the modal opens, and a centred modal re-centres
   as it grows — measured in headless Chromium, the ✕ moved ~300px between the
   open and the content, so a fast click on it landed on a row instead. With
   the top pinned, growth goes downward and the header never moves. */
