 * The flag stays in flow, and the unflagged cards reserve an identical row.
 *
 * Left to itself, the flag pushed the featured card's name, price and allowance
 * rows down by its own height, so the three cards no longer lined up and the
 * prices could not be compared at a glance — which is the entire job of a
 * three-card pricing table. Taking the flag out of flow fixed the alignment but
 * overlapped the card title once the cards narrowed (measured at 375px: the
 * flag spanned x216–334 across a title ending at x318).
 *
 * The reserved row is a hidden copy of the flag rather than a hardcoded height,
 * so it tracks the real thing through any type or spacing change.
