/* Ticket stub design system.
 *
 * The brief was that it must not look like the competition, which is generic
 * purple SaaS. So the whole interface is built around the physical object: card
 * stock, punched tear lines, stubs, and reference numbers in a typewriter face.
 *
 * The perforation is a real repeating radial-gradient of punched holes rather
 * than a dashed border. A dashed rule reads as a divider; punched holes read as
 * a ticket, and that difference is most of the effect.
 *
 * Hand-authored, no framework, no build step, matching every other site in this
 * account. */
