/* Sprocket — reference kit (Tastefolio). A social photo and short-video language built from analog film: photo-print
   post frames with an orange date imprint, story avatars with an exposure ring, short videos on a sprocket film strip
   with edge numbers, profiles and top posts as contact sheets with grease-pencil picks, a rail + feed + side app
   shell (bottom tab bar on phones), story and post viewers, and a creator studio (insights, best-time heatmap,
   messages, schedule). Requires tokens.css; icons are Phosphor (<i class="ph ph-heart">, <i class="ph-fill ph-heart">);
   assets/sprocket.js draws photo scenes, likes, stories, picks and filters. RTL-first. */
