- Replace direct-click-to-jump with a shared comms panel variant that shows LINK ACTIVE/DORMANT status, REQUEST JUMP (disabled while dormant), and CANCEL
- Render gates from the new 256x256 spritesheet (frame 0 body, frame 1 active swirl) with procedural fallback when the texture is missing
- Active gate swirl spins clockwise and breathes alpha between configurable bounds; dormant gates keep the body at full alpha with the swirl hidden
- Wire CommsPanel to a dynamic primary-button action id so the same panel serves world and gate variants
- Add dev probe page (dev/gate-comms.html/.mjs) and update jumpgate/jump-travel tests for the new sprite path, fallback renderer, and comm-window flow
