/*
 * AttenDyn visual identity.
 *
 * Loaded after Bootstrap 5.3, and works mostly by retargeting Bootstrap's own
 * custom properties so existing utility classes inherit the identity instead
 * of every template needing bespoke markup. Bespoke components live at the
 * bottom, under "Components".
 *
 * The subject is a pass system -- badges, QR stubs, serial numbers, a door --
 * so serial data (EK numbers, counts, times) is set in tabular monospace, and
 * the ticket screen carries a real perforation. Two densities share one
 * identity: a calm centred column for attendees on phones, and the dense,
 * high-contrast `.desk` layout for staff working a door for hours.
