/*
 * Settings UI — shared styles for collapsible admin-style panels.
 * ─────────────────────────────────────────────────────────────────────────
 * Admin, Settings, and Brand & Assets each present the same "collapsible
 * card of form fields" pattern (settings-section/header/body), the same
 * status key/value grid, badges, callouts, and form field basics. This file
 * is the single source of truth for that shared chrome so those three pages
 * (and the Site Appearance panel in brand-panel.js) don't each hand-roll a
 * near-identical copy. Pages still own their own page-specific layout CSS.
