/* public/inet-theme.css
 *
 * iNet design system — shared by every dashboard page and the login page.
 * Seven theme presets (theme.js: dark, light, midnight, emerald, amethyst,
 * nordic, sunset) — every colour is a token, see «Tokens» below. Soft
 * borders, one accent per theme, reserved for primary actions, active
 * states, focus and counters. Motion uses transform/opacity only and is switched off for
 * prefers-reduced-motion.
 *
 * settings.html / hub.html also use Tailwind (CDN) for layout utilities;
 * the component classes below (.glass, .btn-brand, .badge, …) keep their
 * historical names so markup generated by settings.js/hub.js stays valid.
 */

/* ---------- Tokens ----------
 *
 * Three layers, all on <html> (theme.js sets the attributes before paint):
 *   1. :root                     the default palette (dark «iNet» theme) and
 *                                everything theme-independent;
 *   2. [data-scheme='light']     structural values for light presets:
 *                                shadows, status text, alerts, chat bubbles;
 *   3. [data-theme='<preset>']   one palette per preset (after layer 2, so a
 *                                light preset can still adjust anything).
 * The accent is one channel: --accent-rgb ("r, g, b") feeds every tinted
 * glow, soft fill and border (rgba(var(--accent-rgb), a)), so a preset only
 * names its colours once. Public names for integrations and custom pages:
 * --bg-primary, --card-bg, --accent-color, --text-primary, --border-glow.
 * The iNet logo keeps its brand orange (--logo-grad) in every theme.
