Minor Changes

• 78b94c5: Accept Liquid-style ?variant=<numeric id> links on product pages.

  • handleShopifyRoutes({routeTemplates}) now 302-redirects ?variant= product URLs to the canonical option-params URL (/products/x?variant=123 → /products/x?Color=Red&Size=M), resolving the variant through the Storefront API with Cache.long() when the client has a cache adapter, following combined-listing variants to their own product page, and stripping unknown or deleted variant ids. When both variant and option params are present, the variant wins.
  • buildProductSelectionSearchParams({style?, selectedOptions, variant?, optionNames, base?}) builds selection link search params, scrubbing stale option and variant params while preserving unrelated ones. style: "variant" emits a shareable ?variant=<numeric id> link, falling back to option params when no variant is resolved.
  • getSelectedProductOptions now treats the variant search param as reserved and never returns it as an option.
  • Registered route redirects can now set an explicit status restricted to 301 | 302 | 303 | 307 | 308.

Patch Changes

• 4ea228e: Reset before and after pagination cursors when collection filters or sorting change.
