/*
 * Web-push soft-prompt banner — initiative 058.
 *
 * In-page opt-in banner shown to authenticated users whose notification
 * permission is still 'default'. The real browser prompt only fires on the
 * CTA click (a user gesture); this banner exists purely to raise opt-in.
 *
 * Theming is automatic: every colour is derived from the project's CSS custom
 * properties (--color-primary, --color-bg-primary, --color-text-primary, …),
 * which flip between dark (:root) and light (html[data-theme="light"]). No
 * theme-specific selectors needed here — the variables carry it.
 *
 * Show/hide is driven by web-push-register.js toggling the [hidden] attribute
 * and the .is-visible class; the class drives the entrance transition.
