+ * Translate a {@link FinalReviewChipEditPatch} into the `Partial<CreateFlowState>`
+ * patch that {@link CreateFlowState}'s update merger should write back. Each
+ * group key targets its own `*DetailsById` (or `coreValueDetailsByChipId`)
+ * record; the patch always merges the new value onto the existing record so
+ * other chips' overrides are preserved.
+ *
+ * The `switch` is exhaustive because {@link FinalReviewChipEditPatch} is a
+ * discriminated union — adding a new facet group in the modal forces a new
+ * `case` here at compile time, which is the whole reason this lives outside
+ * `FinalReviewScreen` (the screen used to host an identical 5-case switch).
+ *
+ * Exported as a pure function so it's unit-testable without React.
