/**
 * #1374 — Packet-route map view a11y + visual modernization.
 *
 * Asserts the rewritten `/#/map?route=N` renderer:
 *   - role-aware shape markers (reuses makeRoleMarkerSVG)
 *   - origin / destination semantically distinct from intermediate hops
 *   - sequence-number badges (separate from label text)
 *   - directional arrows on edges + per-edge aria-label
 *   - per-marker role="img" + aria-label "Hop N of M, <name>, <role>"
 *   - deconflictLabels reused — no overlapping label boxes
 *   - collapsible legend panel renders
 *   - partial-route handling: unresolved markers + "X of N hops resolved"
 *
 * Strategy: the production renderer is split into a pure
 * `window.MeshRoute.render(map, layer, positions, options)` that the test
 * drives directly with synthetic positions, so no DB is required. The
 * production `drawPacketRoute` resolves hops then calls the same function.
 *
 * Run: BASE_URL=http://localhost:13581 node test-issue-1374-route-map-a11y-e2e.js
