/* Product card (oyb/product). Layout from the approved concept board (oyb-site-plan/concepts/Components.dc.html); card
 * frame and buttons copied from the site's live product boxes (the Chroma Skylight review): a 2px light-blue border that
 * turns pink with a soft pink shadow on hover, and pink 8px-corner buttons with an up-right arrow that turn blue with a
 * blue glow on hover, all over 0.3s.
 * Photos always run to the card's edges (no inset tile), framed by the stage (stage.php): a cutout centered on a soft
 * glow (dark on the data card); until a product has one, its database photo on #eff1ff, the color it was shot on.
 * Layout switches on the card's own width (container queries on .oyb-pc; .oyb-pc__in lays out). None of the motion runs
 * for reduced-motion users. */
