/**
 * The advent calendar (`mf/advent-calendar`), layout `grid` — catalogue 01, "Klassisches
 * Gitter" (divb-hq/design/adventskalender.html). With images off and the doors 1–24 it is
 * catalogue 04, the number wall: a switch, not a layout (SPEC K5).
 *
 * Rules target `.mf-adv`, the calendar, never the block wrapper: in the editor the
 * server's wrapper sits inside the editor's own `.wp-block-mf-advent-calendar`.
 *
 * Without the script every door is open: the faces carry `hidden`, the articles show.
 * Under `.mf-adv-js` the state classes the script sets decide — and they are set while the
 * parser inserts each door, before the first paint (assets/advent-calendar/advent-calendar.js).
 *
 * The festive part is the structure and the motion, not a palette (the card). Type comes
 * from the theme; colours are the blog's: ink, grey, hairline, and the orange that carries
 * small text on white at 5.67:1.
