/* ============================================================
   Reviews page chunk.
   Loaded by inc/enqueue.php when is_page( 'reviews' ).

   Visual language: shares typography, tokens, buttons, and divider
   rhythm with the rest of the theme. Hero echoes .hero-pricing
   (text-only, no aurora blobs). Cards reuse the same radius / shadow
   tokens used by .deliverable-card and .testimonial-card.

   Layout strategy: CSS `columns` masonry for the grid — the screenshots
   are intentionally different heights and column flow gives an
   authentic editorial wall instead of forcing uniform rows.
