/* ─────────────────────────────────────────────────────────────────────
 * Flowella — Home Problem Comparison
 * Two-card vs-grid with central arrow.
 *
 * The phone illustrations (LEFT chat / RIGHT Flow) intentionally mirror
 * the styling used on /use-cases/* detail pages (`.wa-phone`,
 * `.wa-flow-preview` in `styles/hubdb-use-case.css`) — but with `vs-`
 * prefixes so they render correctly on the home page (which does NOT
 * load `hubdb-use-case.css`). Keep the shared visual language: dotted
 * WhatsApp wallpaper, white message bubbles, green outgoing bubbles,
 * green submit pill, etc.
