/* Queeny chat assistant ("Trợ lý tự động"). Everything is built by bot.js and scoped under .qbot: without JS nothing renders.
   The assistant only speaks when asked, so at rest the page shows only: on wide screens during the hero, a small card
   (header, chips, input) at the bottom left; everywhere else a round launcher that opens a drawer.
   States on the root: data-win = off | panel (the hero card) | drawer, data-mode = hero | dock,
   .dock-on (launcher wanted), .is-blocked (Zalo dialog, menu, lightbox or 3D phone sheet open), .is-ready.
   Motion is transform and opacity only. Reduced motion: base.css stops transitions, bot.js skips every animation. */
