- Introduce data/gates.json + js/galaxy/JumpNetwork.js: a strongly-connected, degree-limited spanning tree over the nearest-star graph (plus local shortcuts) so every system holds 1–3 gates, all jumps are local, and no system is closed or trapped
- Place each gate on the tether circle of an anchor (planet / space station / home world), facing its destination star; enforce radius band, clearance from anchors, and gap between gates in SystemGenerator.layoutGates
- Add the JumpGate entity (procedural twin-pylon portal) with the same solid contract as Planet/Station, discoverable in cyan, listed in the HUD dossier; wire into GameScene solids + discovery
- Guarantee every system holds at least one gate anchor (barren systems get a deep-space station); cap the home system at 3 objects so it fits the tighter band
- Rework solar-system layout to a full pairwise band [minSpacing, maxSpacing] with rotation tuned toward gate bearings; update tests and docs accordingly
