Shopify gives every single-variant product one option named Title with the
lone value Default Title. It isn't a real choice, so filter it out of the
product detail options, the cart line summaries, and the payload the store
assistant sees. Variant matching still reads the raw selectedOptions, so
single-SKU products keep resolving their variant.

- /api/chat streams via AI SDK v7 through OpenRouter (OPENROUTER_API_KEY),
with a store-specific system prompt and five read-only tools:
searchCatalogue, getProductDetails, listCollections,
getCollectionProducts, browseProducts
- Sidebar assistant on the right that opens from a launcher and expands,
built on ai-elements (conversation, message, prompt-input, tool) with
shimmer on in-flight tool calls
- Extract services/shopify/catalog.ts so the Storefront fetchers have no
React imports and can run in a Route Handler; the client hooks now
re-export from it
- ai-elements pulled in the canonical shadcn primitives, replacing the
hand-rolled command/dialog/button variants; search dialog moved to the
cmdk-based Command and CommandDialog forwards shouldFilter
- Pin shiki to ^3.19.0 to match streamdown and drop the duplicate copy
- Add .env.example documenting the required env vars
