/* FCS.Blazor.Irc — IRC client styling.
 *
 * Colours come from the shared --fcs-* tokens (FCS.Blazor.Shared/fcs-theme.css), which the host must
 * link. Nothing here names a colour, so the client follows the host's light/dark toggle; see that
 * sheet for why --rz-base-N00 must not be used and why the surfaces are mixed rather than fixed. */
