/*
 * Floating chat widget.
 *
 * Colours are custom properties with fallbacks, so this stylesheet stands alone
 * and can be rethemed by overriding a property on any ancestor. Values derived
 * from the accent — glows, hover tints — use color-mix() against the same
 * property, so a single override carries through instead of leaving a pink glow
 * around a blue widget. See the Theming section of README.md.
 *
 * color-mix() needs Chrome 111 / Safari 16.2 / Firefox 113 (all 2023).
