/* ===========================================================================
   SiteBot
   ===========================================================================
   Everything is scoped under .sitebot. The colours come from the site's own
   custom properties, so the card follows whichever theme is active -- and every
   one has a fallback, so it still looks right dropped into a page that has none
   of them.

   Only inline-level elements are used (see init.php), which is why every block
   here is a span set to display:block or flex.

   Two modes. data-mode="card" is an ordinary block in the page. data-mode="bubble"
   is a floating Help icon; sitebot.js moves it onto <body> so it shows on every
   route, and positions it with a transform (see "Bubble mode" below). The visitor
   can drag it anywhere, toss it, and it drifts to the nearest window edge.
