Replaces the hand-rolled shopifyFetch wrapper and raw query strings with
the hydrogen preview package (0.0.0-preview-116d5d7-20260730141607), the
same build pinned in hydrogen-preview/.
- services/shopify/client: createStorefrontClient({type: "public"}) with a
static request context. Two module-scoped clients — uncached for carts,
products and customers; revalidate-3600 for shop policies — using the
client's custom fetch option to carry Next's caching hints.
- graphql/*: every document wrapped in gql(), fragments composed via the
second argument instead of string interpolation, and $country/$language
declared with @inContext so hydrogen injects them.
- shopifyFetch keeps its {query, variables} call shape so call sites are
unchanged, but is now generic over the document, so data is inferred. It
re-raises GraphQL errors, which hydrogen returns rather than throws.
Env var names, the 2025-07 API version pin, and the client-side fetching
architecture are unchanged.
Turning on type coverage surfaced real defects, not just annotations:
- hydrogen gql check caught $discountCodes: [String!] used where the field
requires [String!]!.
- Cart and customer mutation payloads are nullable and were dereferenced
unconditionally, so a failed mutation threw a TypeError. Adds a shared
unwrapCartPayload helper (collapsing five copies of the same userErrors
check) and explicit null handling in the customer service, so a null
payload reads as an error rather than success with no errors.
- Search results are a Product | Page | Article union; adds __typename to
the queries and narrows on it.
- Widens nullable fields (altText, image, customer.email, totalTaxAmount)
in the domain interfaces and in the structural duplicates some
components declare locally.
Adds a typecheck script (tsc --noEmit && hydrogen gql check); it passes
with 0 errors. Two deprecation warnings are left alone as acting on them
would change behaviour: ProductOption.values and CartCost.totalTaxAmount.
Verified against mock.shop: build prerenders the policy pages through the
cached client, and in the browser the product grid, search with facets,
collection filter round-trip, add-to-cart and quantity update all work.
Customer account flows are untested — they need real credentials.

The assistant only ever renders prose, links and the odd list, but
Streamdown's plugin set dragged in shiki, mermaid and katex — and
streamdown core declares mermaid as a hard dependency, so dropping the
plugins alone would have left it installed. Rendering now runs on the
same unified pipeline Streamdown used internally, minus the plugin
surface: remark-parse -> remark-gfm -> remark-rehype -> rehype-sanitize
-> hast-util-to-jsx-runtime. GFM, streaming repair and the link-safety
hook all survive; fenced code renders as plain <pre>. Net -264/+101
packages.
remend now runs only while a part is still streaming. On settled text it
reads `*$89*` as an unclosed italic — the `$` throws off its
closing-delimiter scan — and appends a stray `*` that parses as an empty
bullet. Italic prices are ordinary storefront copy, so that would have
shown up in production.
Route-relative links go through next/link in the same tab; sending a
shopper to a product page in a new tab would strand the conversation
behind it. Only external destinations get the confirmation dialog.
code-block.tsx and tool.tsx were the sole users of shiki and had no
importers, so both are gone.
Also folded in two unrelated changes that were already in the tree: the
loader move out of app/components/ui, and dropping the fade on the
command palette so it opens instantly.

- Gate the assistant on NEXT_PUBLIC_ENABLE_AI=1 (UI only; the /api/chat
route still responds if called directly)
- Chat model is openai/gpt-5.6-luna-pro with reasoning requested and
sendReasoning enabled, rendered via the Reasoning component
- Suggestion chips and reasoning come from ai-elements; attachments gain
hover-card previews, left alignment, and render under the user message
- Launcher: plain Button when closed, magicui RainbowButton when open
- Tool results replace the collapsible Tool UI with a shimmer while
running and a muted icon + summary line after, plus product previews
- Commerce icons in place of the folder icon for collections
- Add a thin announcement bar above the header; footer splits links and
socials onto separate rows and clears the launcher corner
- Add the shadcn base layer so Tailwind v4's bare `border` picks up the
theme colour instead of currentColor

- /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
