/* ============================================================
   FAQ CHATBOT WIDGET — SCOPED STYLES (assets/css/chatbot.css)
   Design tokens (--ink, --ivory, --marigold, --maroon, --gold-soft,
   --shadow-card, --ease, etc.) already live in main.css and are
   enqueued site-wide. This file loads on top of that, site-wide
   (everywhere the shared footer renders), via
   wp_enqueue_style('adharva-chatbot', ...) — see functions.php.

   Ported from the static homepage's "STICKY HELP CHATBOT" block
   and hardened for production:
   - honours prefers-reduced-motion
   - iOS safe-area aware positioning
   - clearer focus states for keyboard users
