/* ================================================================
   Full-page chat app (Pages/Chat.razor), ported from the Dashboard's
   Pages/Chat.razor.css.

   Every selector is SCOPED under .chat-page-container (the page's root
   element). The Dashboard shipped these rules globally, which is safe there
   because chat is most of that app — but in the portal 16 of the 41 class
   names already exist (.chat-input, .people-list, .connection-status, .dot …),
   some in map.css and some in unrelated pages such as AdminTax and Alerts.
   Unscoped, this file would restyle them.

   Keyframe bodies are left alone; only rule selectors are prefixed.
   ================================================================ */

/* Main container */
/* ⚠ min-height: 0 on every link in this flex chain, or the input will not stay at the bottom.

   A flex child defaults to min-height:auto, which means it REFUSES to shrink below its own
   content. A chat window taller than the viewport therefore grows instead of scrolling, and the
   input bar - correctly flex:0 0 auto - ends up below the fold, at the bottom of the CONVERSATION
   rather than at the bottom of the PAGE. .chat-content and .chat-messages already had it; the two
   containers around them did not, which was enough to break the whole chain. */
