/* Issue #1109 (post-#1174 conversion) — Long-tail routes reachable on phones.
 *
 * Original contract: tapping the hamburger surfaces the long-tail routes
 * (Tools/Lab/Perf/Analytics/Observers/Nodes) that don't fit in the primary
 * nav. Origin used a CSS-clip-prone dropdown.
 *
 * #1174 replaced the hamburger-at-narrow-widths path with a 6th "More" tab
 * in the bottom-nav that opens a bottom-anchored sheet listing the same
 * long-tail routes. The hamburger is HIDDEN at ≤768px (its job at narrow
 * widths is now done by the More tab).
 *
 * This test asserts the converted contract:
 *   1. At iPhone-13 viewport (390×844, mobile UA), #hamburger is NOT visible.
 *   2. The More tab IS visible and toggles the sheet.
 *   3. Tap More → sheet visible (pixel-level: elementFromPoint inside sheet,
 *      bounding rect non-zero, top above the bottom-nav).
 *   4. Tap a long-tail route inside the sheet → URL hash updates AND
 *      sheet closes.
 *   5. Tap More again → sheet re-opens (toggle, not push).
