/*
 * Publication chat box: look and feel.
 *
 * Loaded by the plugin by default. To manage these styles in the theme instead, paste this file into the
 * theme stylesheet and untick "Load the plugin's chat box styling" in Settings > Publication Chat.
 * (Functional styles such as the streaming caret live in chat.css and always load.)
 *
 * Colours come from the theme's custom properties, with fallbacks so the box also works elsewhere:
 *   --urbedtrust-canopy     the green frame
 *   --urbedtrust-darkgrey   text
 *   --urbedtrust-transport  the Ask button
 *
 * Design: the brand-green frame holds only the heading (large white text passes contrast on the green);
 * everything a visitor has to read sits on a white panel inside it.
