/**
 * Cards (design-system.md §5).
 *
 * One structure, four content variants. Only the article variant exists at M3,
 * because related guides need it; template, product, and topic-door land with
 * the card grids in M5.
 *
 * **The whole card is one link.** The `::after` overlay stretches the title's
 * anchor across the card, which gives a full-card hit area with exactly one
 * focusable element — no nested interactive traps, and the title is the
 * accessible name.
