/**
 * upcomer/highlight-card-row
 *
 * Tinted gray canvas with white cards "lifting" off it. Each card has a red
 * accent: by default a solid rule across the top edge with a subtle dark hairline
 * on the other three sides; an alternative variant wraps the card in a full
 * red border (no top rule).
 *
 * Compliance with the "no new colors" rule (CLAUDE.md → Design conventions):
 * the canvas (very light gray) and the card (white) are intrinsic to the
 * block's visual definition — they ARE the contrast that makes "lift" work,
 * not palette colors. The red accent is exposed as an editor-controlled
 * Color Picker field (`accent_color`) following the page-hero-intro pattern;
 * the default red here is the per-block fallback when the editor leaves the
 * picker empty.
