   Product-screenshot component library.

   Every visual slot identified in docs/visual-proof-audit.md renders
   through one of these patterns. Images are real files in
   /images/product/ — replacing a placeholder is a file swap, not a
   markup change.

   Companion behaviour lives in /js/shots.js (lightbox + tabs).
