Centra storefront patterns: PDP variants, size guides, notify-me, and Instant Nav. What broke, then the fix.
Product cards imported commerce and CMS types until a field rename broke the card. Map to storefront types and keep vendor packages out of components.
Collection pages stuck on loading after Instant Nav. Own PLP slugs per locale, 308 the rest, and skip waiting on empty query strings for the shell.
A fashion PDP that greys out add to cart until size is picked looks broken. Validate on submit, show the hint after a miss, then focus the chips.
Colour swatches showed Black twice on a fashion PDP. Dedupe siblings on the URL you paint, then hide the picker when only one colour exists.
Fashion size guides store measurements as rows. Shoppers need size rows on the product page. Flip the sheet once so the numbers match the layout.
An out of stock size on a fashion product page should not grey out checkout. Flip the main button to a notify action and reuse one overlay for every sheet.
Fashion checkout mail never arrives if you invent the event names. Copy the plugin tags and split the catalog id so receipts and restock emails actually send.
