/**
 * Dev: real-input test for the GATE comm window (v0.5):
 *
 *   clicking a gate NO LONGER jumps (or fly-heres) — it opens the
 *   shared comms panel in its gate variant (js/ui/CommsPanel.js):
 *
 *   1. click a DORMANT gate  → window opens: LINK … DORMANT,
 *                              REQUEST JUMP grayed (disabled), CANCEL;
 *                              the ship does NOT fly to the gate
 *   2. click CANCEL          → closes, no jump seam fires
 *   3. click an ACTIVE gate  → LINK … ACTIVE, REQUEST JUMP enabled
 *   4. click REQUEST JUMP    → the jump seam fires with the gate
 *                              entity (jumpThroughGate) + closes
 *   5. ESC                   → closes
 *   6. gate window open, click ANOTHER gate → the window re-anchors
 *                              on that gate (name + position)
 *
 * Real DOM mouse events hit the canvas (Phaser's input manager), so
 * this exercises the full path: scene pointerdown → gateAt →
 * openGateCommsPanel, and the panel's own button dispatch
 * (commsAction).
