/**
 * E2E (#1630): Reach page mobile layout.
 *
 * On narrow viewports (393×800 and 360×740 — common iPhone/Android sizes)
 * the /#/nodes/{pubkey}/reach page must:
 *  - Shrink the map height (#nqMap) to ≤ 320px so stats/table are visible
 *    above the fold instead of being pushed below a 420px-tall map.
 *  - Lay the 6-column link table out so its scrollWidth ≤ clientWidth (no
 *    horizontal scroll inside the table).
 *
 * Desktop guard (≥768px / 1440×900): map height must remain the original
 * 420px and the table must still render 6 visible columns — no regression.
 *
 * Run: BASE_URL=http://localhost:13581 node test-issue-1630-reach-mobile-e2e.js
