/* ==========================================================================
   Core Markets — expanding cards. Hover for pointer users, focus-within for
   keyboard users, and a .is-expanded class (toggled by market-cards.js) for
   touch/tap. The grid-template-rows 0fr→1fr technique animates height
   without JS measuring pixels, and degrades to "just show the content" if
   JS never runs (see .market-card--no-js below).

   card, horizontally or vertically, at 3 columns. */

   Uses the same grid-template-rows 0fr↔1fr technique as .market-card__panel
   below (just inverted: this collapses shut on the same hover/focus/tap
   triggers that open the panel), so opening a card feels like one
   continuous motion — the image folding away to make room for the detail
   content — rather than two unrelated animations. Cards with no matching
   project photo simply omit this element; .market-card__toggle's own
   padding-top provides the spacing in that case. ---- */
