/*
 * chat.css — the chat corner's look (#655), served at /m/chat/chat.css. Linked
 * by the engine on /chat; a page that places a [data-chat-slot] gets it linked
 * by chat.js. Generic: no tenant colour or name here.
 *
 * Every rule is under the .uzc root class, and every element chat.js makes is
 * first reset (`all: revert`, the browser's own defaults) at the weight of the
 * root class plus the element, so neither the engine page's member-area rules
 * nor a tenant page's own rules reach in; our rules carry two classes or more.
 *
 * Colours and fonts are the site's --uzj-* properties, measured on the event
 * page by /features.js (#644) and set by chat.js; without them, the app page's
 * own palette (--fx-*), and last neutral values. Light and dark both read.
 * Sizes are fixed where something fills in later (the status line, the tools,
 * the composer), so nothing moves when it does. Reduced motion is honoured.
