/* toasts.css — iOS notification-banner-style flash messages.
 *
 * Replaces the saturated tinted-background flashes (bg-{emerald,
 * sky}-50 etc.) that clashed with the Apple-HIG primitives the
 * rest of the app uses. Reference: an iOS push that drops from
 * the top with a soft spring, lingers, can be dismissed.
 *
 * Visual language:
 *   * Near-white (light) / near-black (dark) background with
 *     `backdrop-filter: saturate(180%) blur(20px)`.
 *   * Hairline border + soft layered shadow.
 *   * 3px wide colored accent stripe on the left edge — green
 *     / amber / red for success / warn / error. **Stripe only,
 *     not a full tinted background** (CLAUDE.md "no traffic-
 *     light pills" rule).
 *   * 32×32 logo (school logo from SchoolSettings or the
 *     Syncc mark fallback) with 8px corner radius — matches
 *     the iOS app-icon shape.
 *   * Drops in from the top with a 350ms spring; auto-dismiss
 *     5 s success / 8 s info / sticky on errors.
 *
 * Brand tokens (`--brand-*`) auto-swap in dark mode via the
 * `.dark` scope from `brand.css`.
