// Phase 23 end-to-end coverage for the Report View. Mocks the
// gateway with a single seeded report that fills every wire field
// the orchestrator's sections render, then drives the page through
// the targeted-test contract:
//
//   1. Every TOC anchor click scrolls the matching section into view
//      and the section is present in the DOM with at least one row
//      (or its empty-state copy when it is intentionally empty).
//   2. Snapshot save/restore on the active-view-host scroll
//      container survives a /map navigation round-trip.
//   3. The "back to map" button navigates to the map URL.
//   4. The mobile <select> fallback scrolls a section into view on
//      a narrow viewport.
