/**
 * Support desk.
 *
 * Layered on /theme.css, which owns the tokens, the base typography and every
 * shared component. This file holds only the conversation: the transcript, the
 * bubbles and the composer.
 *
 * The bubbles deliberately do not use the brand colour as a fill. --accent is
 * whatever the panel administrator set it to, and white-on-arbitrary-hue is a
 * coin flip for legibility; the visitor's own messages are distinguished by an
 * accent rail and a tinted surface instead, both of which keep body text on a
 * theme-aware --ink token in either theme.
