// Variation values are often term slugs ("1-קג"), not the parent's display names ("1 ק\"ג"). Each value
14 // resolves to the parent's declared choice: exact, then percent-decoded, then a unique slug match.
15 // A value that still does not resolve is left as is; the route refuses it (a gap), it never guesses.
16 //
17 // Two parent attributes may share a label. Attributes are matched by position: a variation
18 // attribute matches by id when both ids are set, otherwise by name, and each one is used once.
19 // Every record choice carries `attributeIndex` (the parent selector position) so the route never
20 // relies on the label.
21 //
22 // Input: the WC REST product (`attributes[]`) and its variations (`attributes[]`, `menu_order`, `id`).
23 // Output: { selectionAttributes, records: [{ variationId, choices: [{ optionName, choiceName, attributeIndex }] }] }.
24 // The caller maps each record's price, sale price, SKU and stock as it already does and puts
25 // `choices` on the canonical variant.
