/* Relay chat bubble.
 *
 * Two copies of this file exist and are meant to stay byte-identical:
 * Relay/assets/chat-widget.css (relayapp.pro) and
 * archon-ios/docs/css/shaggoth-widget.css (docs.relayapp.pro). Change one,
 * copy it to the other -- the widget this replaced rotted precisely because
 * each site kept its own fork of it.
 *
 * Both sites use the same palette under different variable names:
 * relayapp.pro sets --bg2/--text/--text-dim, the docs site sets
 * --bg-secondary/--text-primary/--text-secondary. Each lookup tries the Relay
 * name, then the docs name, then a literal -- so the widget tracks whichever
 * site it lands on, and still looks like itself on a page that defines
 * neither.
