/**
 * Coverage route reachability on mobile navigation.
 *
 * The "Coverage" route (#/rx-coverage) is opt-in: roles.js injects its link
 * into the DESKTOP top-nav (.nav-links) only, when window.MC_CLIENT_RX_COVERAGE
 * is true. The two mobile navigation surfaces build their long-tail route lists
 * independently:
 *   - public/bottom-nav.js  → the "More" sheet (phones, ≤768px)
 *   - public/nav-drawer.js  → the edge-swipe drawer (tablets, >768px)
 * Both used hardcoded arrays that omitted rx-coverage, so when Coverage was
 * enabled it was present on desktop but UNREACHABLE on mobile. This test pins
 * that, once enabled, Coverage appears in BOTH mobile surfaces, ordered right
 * after Analytics (matching the desktop top-nav insertion point).
 *
 * Skips cleanly when:
 *   - Chromium is unavailable (unless CHROMIUM_REQUIRE=1 → hard fail), or
 *   - the deployment under test has clientRxCoverage disabled (default off).
 *
 * Stable selectors consumed here:
 *   [data-bottom-nav-tab="more"]                  — More tab (opens the sheet)
 *   [data-bottom-nav-more-route="rx-coverage"]    — Coverage row in the sheet
 *   window.__navDrawer.open()                      — opens the edge-swipe drawer
 *   [data-nav-drawer-item="rx-coverage"]          — Coverage row in the drawer
