/**
 * SHIP console → CARGO HOLDS → BEST EXITS tap test (dev tool, Node, no
 * browser):
 *
 *   node dev/ship-cargo-dest.test.mjs
 *
 * The bug this guards: the bay manifest listed a held good's charted exits
 * as pure TEXT — clicking a destination did nothing, so the player could
 * never set a route from the ship console. The rows are now tap surfaces and
 * CONFIRM routes the ship through the map's own seam (GameScene.setDestination),
 * exactly like the planet shop's scout panel (js/ui/shop/ScoutPanel.js →
 * SurfaceScene.askSetDestination).
 *
 * Asserted with the REAL js/ui/ShipWindow.js over the real data files + a real
 * generated galaxy (a stub scene — phaser-loader.mjs swaps in dev/phaser-stub.mjs):
 *
 *   - HOSTING: the confirm is a ConfirmOverlay CHILD of the window at depth 30
 *     (above the plate / feed / glitch layers) — it can never be hidden behind
 *     the console it belongs to, which is what "not visible to the player" was;
 *   - THE ROWS: every charted exit row is tappable and carries onTap(); the row
 *     for the system the ship is IN reads HERE and has no tap surface;
 *   - THE ASK: tapping a row opens the dialog with data/shipScreen.json →
 *     cargo.detail.setDestination's title / SET DESTINATION / CANCEL labels and
 *     body lines built from the exit (world, system, class, price, margin);
 *   - CONFIRM: fires onSetDestination(systemId, objectId) for that exit's own
 *     WORLD once the collapse lands — and only then;
 *   - CANCEL / scrim: closes with no destination written;
 *   - CLOSE: taking the console down takes the dialog with it (no orphan scrim
 *     swallowing clicks);
 *   - A repaint while the dialog is up (the 250ms telemetry poll) never drops
 *     it.
