/* recycle.reviews — Community pinboard wall
 *
 * Typography reference (per DESIGN.md):
 *   Display:  Permanent Marker (Google Fonts) — casual brush, site title
 *   Body:     Merriweather (Google Fonts) — sturdy slab-adjacent serifs are
 *             designed for screen readability while maintaining a warm,
 *             slightly old-fashioned quality (traditional serif).
 *   Meta:     Karla (Google Fonts) — clean geometric sans-serif, with Inter
 *             listed as a stack fallback.
 *
 * Interactions referenced in code: Intersection Observer (threshold: 0.1),
 *   bounce-enter cascade, spring scale-hover on push-pins and stamps.
 *
 * (Hover Interaction:** uses cubic-bezier spring; rating stamps echo
 *   Merriweather's serif weight via inline-flex of border-stamped circles.)
