/* =============================================================================
 * LITSLINK BLOCKS — Intro · explained cards + stat
 * (acf/ll-explained-cards-stat)   Handle: pb-ll-explained-cards-stat
 *
 * Self-contained: the design palette is scoped to .block-explained-cards-stat
 * (no :root leak) and fonts fall back to a literal Montserrat stack so the block
 * styles correctly without the shared tokens sheet (inserter preview). The
 * shared .block-head rules use LITERAL font-family + #hex (NOT block-scoped
 * vars) per the shared-head collision rule.
 *
 * E-Commerce mockup §02 "What Are E-Commerce AI Agents" + §09 "Vision for the
 * Future": light section, intro cell + blue-gradient stat card + white icon
 * cards. Two layouts:
 *   --grid  : 2×2 grid → row1 intro | stat, row2 card | card.
 *   --split : 2-col → LEFT intro + stat stacked, RIGHT white cards stacked.
