/*
 * kink.town theme for ejabberd's mod_invites pages (Nightcap: brass on ink)
 * --------------------------------------------------------------------------
 * Replaces Bootstrap 5, which ejabberd normally ships separately. The
 * templates keep their Bootstrap class names, so this file implements only
 * the classes they (and static/invite.js) actually use. Upstream template
 * updates should keep working; if a new template uses a class not covered
 * here it will simply render unstyled.
 *
 * invite.css still loads after this file. It reads Bootstrap's colour
 * variables (--bs-info-rgb etc.), which are defined below in the Nightcap
 * palette.
