/**
 * User stories covered: Feature 21 — Edit highlight on resubmitted PO
 *   - When a MANAGER reviews a PO that was resubmitted after edits were requested,
 *     changed fields are visually highlighted (ring-, border-warning, bg-warning, etc.)
 *
 * Implementation context (po-detail.tsx):
 *   - The `resubmitSnapshot` is stored in the SUBMITTED action's metadata when
 *     a submitter resubmits after EDITS_REQUESTED.
 *   - po-detail.tsx uses `originalLineItems` and renders a diff label.
 *   - Changed line items get strikethrough styling (old values) and bold new values.
 *   - Header fields (vessel, vendor, etc.) use a ring/border highlight when changed.
 *
 * To drive this flow:
 *   1. Tech submits PO
 *   2. Manager requests edits (with a note)
 *   3. Tech edits the PO and resubmits
 *   4. Manager reviews — changed fields should be highlighted
