/*
 * ix-chat.css — the consumer's half of the driver seam.
 *
 * `italix/chat` emits class names and no styling, on purpose: a library that
 * shipped a stylesheet would fight every consumer's design system. This is the
 * stylesheet for this consumer, and it is the whole of it.
 *
 * Two constraints it is written under, both of which come from where the widget
 * ends up rather than from taste:
 *
 * 1. **Nothing here may leak.** Every selector is under `.ix-chat-launcher`,
 *    and no element selectors are used, because this file is eventually going
 *    to load on somebody else's WordPress page. (The embed script will put the
 *    whole thing in a shadow root, which makes this belt as well as braces —
 *    but the braces are what work today, on the demo page.)
 * 2. **The host page's fonts and colours are not assumed.** Sizes are in rem
 *    against an explicit base, colours are declared here, and the dark variant
 *    is by `prefers-color-scheme` rather than by a class the host would have to
 *    set.
