/*
 * Shared card system — one four-field article card (title, short description,
 * date, primary-category pill) used by the home bento and the article's related
 * blocks.
 *
 * The type scale is driven by the card's OWN inline size (`container-type:
 * inline-size` on `.fm-card`, `cqi` in the fluid term) and capped per screen band
 * through rem-based breakpoints — a narrow sidebar card on an ultrawide monitor
 * keeps a sidebar-sized title.
