/*
 * mw-card: a white card on the ground (docs/design-system.md, spec §5, D14).
 * Cards are never nested. Semantic tokens only; MwComponentPurityTest holds it.
 *
 *   mw-card         the card: border and a soft shadow, since white meets the
 *                   ground at only 1.11:1
 *   mw-card__icon   a navy glyph on the selected blue, tap-target sized
 *   mw-card__title  the card's heading (pick the h level the page needs)
 *   mw-card__text   its body text
 *   mw-card__cta    its one link (mw-link) or button (mw-btn), bottom right;
 *                   it only places what it sits on, never pads it
 *
 * A card with one destination is a stretched link (spec D15): never wrap the
 * card in <a>.
 *   mw-card--link   the card is the target: it lifts and its title underlines
 *                   on hover, and it shows the focus ring when its link has focus
 *   mw-card__link   the one <a>, inside the title; its ::after covers the card
 *   mw-card__more   the visible "See how →", aria-hidden decoration under the
 *                   text, left aligned, at the bottom
 *   mw-card__actions a card with more than one action: its buttons in a row,
 *                   left aligned, at the bottom
 *   mw-card__actions--stack the same buttons one above another; with
 *                   mw-btn--block each fills the card's width
 *
 * Optional parts for cards in a list a reader compares (spec D15):
 *   mw-card__tag    a small label above the title: platform, audience, type
 *   mw-card__meta   a header strip, what it is on the left and one fact on the
 *                   right, divided from the body; for a card with no padding
 *   mw-card__meta-fact the fact on the right of the strip
 *   mw-card__body   the padded body under an image or a meta strip
