/*
 * Congress listing cards (resources/views/app/congresses/partials/congress-card.blade.php): /congresses and its
 * facet pages, the no-results suggestions and a series page's next edition.
 *
 * Each card is a ticket: the city's photo, the congress, and a stub with its dates, behind a perforated line with
 * a notch cut out at each end. The layout follows the width of the list (container queries on .cbCardList), not
 * the screen, so the card fits whatever column it sits in:
 *   > 700px   photo | congress | stub
 *   <= 700px  photo | congress, the stub as a row underneath
 *   <= 520px  compact: small square photo, about four cards per phone screen
 *
 * Site tokens: navy #333d4c, yellow #fddd01, purple #6433a1, border #e5e8ef, Nunito.

 * hole 1px larger around the same centre. What stays visible between the two holes is the border.

 * .cbCardIn's box (1px in): on wide cards the top and bottom of the stub's dashed edge.
