/*:*
* ggaze — responsive navigation integration test
*
* Fires 10 rapid next-actions (async loads) and asserts last-write-wins: after
* the main loop drains, the viewer shows the final current image, not a stale
* intermediate. Also confirms the rapid navigation did not block (the loop
* completes and the final texture arrives within a timeout). Needs a display
* (integration suite; CI uses xvfb).
