caty_render_product_cards

Search products matching the user query and render them as an interactive carousel in the chat widget. Use this tool when the conversation is about products, prices, availability, or recommendations, because clickable cards are more useful than a plain text list. Returns a UI action payload the frontend renders as clickable product cards. For follow-up refinements: when the user sends a short message (1-2 words) like "handmade", "negru", "ieftin" after a product query, this is a refinement — combine it with the previous product context. Example: user asks "frunze decorative" then says "handmade" — query should be "frunze decorative handmade", not just "handmade". Check conversation history for product context. RESPONSE: UI action payload rendered by the chat frontend as an interactive product carousel. Do not re-list the products in text after calling this tool — the cards are already visible to the user.
