/* The "Ask us" assistant (app/chat.php, static/js/chat.js, docs/CHAT.md). Uses the tokens of vizwalk.css (one dark
   theme); the fallbacks after each var() keep it readable on a page without them. Logical properties only, so an
   Arabic page mirrors it. Phones: the button sits above the sticky contact bar; the panel is a bottom sheet. */
