/**
 * Feature Card — shared frontend + editor styles.
 *
 * One stylesheet drives both contexts (block.json registers this as `style`),
 * so the canvas and the front end resolve identical geometry. editor.css only
 * adds affordances the front end has no use for.
 *
 * THE CURVED EDGE
 * ---------------
 * The card colour bulges into the photograph — widest at ~26% of the card's
 * height, narrowest at the bottom. That is drawn by *removing* the matching
 * sliver from the image with a CSS mask, not by painting a shape on top of it.
 * The card's own background then shows through, so the curve stays correct for
 * any card colour without the colour being written down twice.
 *
 * The mask SVG carries `preserveAspectRatio="none"`, so its 100x100 viewBox
 * stretches to whatever the media pane measures — the curve scales with the
 * card instead of drifting out of it. Where masks are unsupported the image
 * simply keeps a straight edge; nothing else changes.
 *
 * Path coordinates are percentages of the media pane, traced from the approved
 * design: the bulge peaks at 8.4% of the pane's width, 26% down.
 *
 * Tokens come from theme.json — see DESIGN.md.
