   ShopperAI components  —  assets/css/shopperai-components.css
   Lahav's app-shell + component patterns (dashboard & Shelf-Pager demo), re-based on brand tokens.
   Requires shopperai-tokens.css (and shopperai-glass.css for the glass look). All classes prefixed sa-.
   Written with logical properties so the same CSS serves RTL (Hebrew, default) and LTR.
