/* /connect demo: the widget (a07-widget; round two b4-widget). The YDO Connect chat in the business's colours, after
   src/templates/widget-desktop.html (900 and up: a 420-wide card above the bubble) and widget-mobile.html (below 900:
   the whole browser viewport, with its own close). Every colour is a token; the product's own colours map to the nearest
   (bot bubble #f0f4f8 -> --ground-2, system line #fff3cd/#856404/#ffeaa7 -> the --recall set, a person's bubble #2196F3
   -> --std-pill, the question pills' standard #2563eb -> --std-pill). Hover moves colour and border only and lives in
   (hover:hover); motion is opacity and transform only. Spacing on a 4px grid; the slot can be as short as ~280px, so the
   head and the composer step down with the slot's height (container queries on .dc-w-box). The transcript's top --w-pad
   is a fade (a row passing under it fades out, never a hard cut) and is where the widget seats the row it places. */
