/**
 * Ask The Expert - frontend styling for the real, wired panel.
 *
 * Deliberately layered ON TOP of the theme's own .da-expert-demo/
 * .da-expert-field/.da-expert-submit rules (main.css) rather than
 * duplicating them - this file only styles what did NOT already exist in
 * the theme (the disabled "coming soon" look, the response timeline, the
 * accordion, citation cards, rating buttons) and overrides the small
 * number of theme rules that were specifically styled for the old
 * disabled state (dashed borders, not-allowed cursor, muted submit
 * button). Enqueued with a dependency on the theme's own stylesheet so
 * these overrides always load after it - see class-frontend-renderer.php.
 * Uses ONLY the theme's own existing --da-* custom properties - no new
 * color/spacing tokens are introduced.
 *
