/*
 * "SHOW THE ITEM NUMBER" AND THIS CONTAINER ARE MUTUALLY EXCLUSIVE.
 *
 * `container-type: inline-size` is shorthand for `contain: layout style
 * inline-size`, and STYLE CONTAINMENT SCOPES CSS COUNTERS. Every counter used
 * inside a style-contained element is independent of every counter outside it.
 *
 * The item number is a counter: `counter-reset: li` on `.block-loop-index`
 * (musiveo-loops build/style.css) and `counter-increment: li` on each card's
 * `::before`. With each card turned into its own containment scope, that
 * increment never reaches the reset on the wrapper, so every card counts from
 * its own zero and the row reads
 *
 *     1  1  1  1  1
 *
 * It is right in the block editor and wrong on the front end purely because the
 * container is a front-end/presentation concern; the numbering is pure CSS, so
 * there is no JavaScript or PJAX timing involved.
 *
 * So a numbered loop opts OUT of the container and keeps its stacked header
 * layout at every width. The trade is deliberate: a numbered row keeps working
 * counters instead of a two-column header, and every non-numbered row - the
 * overwhelming majority - keeps the 440px title/actions layout unchanged.
 *
 * The `:not()` above covers the class on the same element as the row; the rule
 * below covers `.block-loop-index` arriving on an ANCESTOR instead.
