/* ATLAS V6 — Voice Inbox / Notification Center page augmentation
 *
 * V5→V6 polish 2026-06-23. Re-skins the existing ntf-* BEM DOM
 * (data-view="notifications", id="view-notifications") with V6 vocabulary
 * per atlas-dashboard.md. Distinct from the top-bar bell drawer.
 *
 * Loads after css/v5-notifications.css + before css/v6-pages.css. No class
 * renames — v5-notifications.js still self-inits on atlas:view-shown. Dark
 * mode blocks omitted per atlas-dashboard hard rule #4 (V6 single-theme).
