=== 0.0.18.5 - Phase 7A Game-tab-only Phayriosis button ===
User test of 0.0.18.4 confirmed the Phayriosis button was positioned correctly beneath Allow Cheats on the Game tab, but it reappeared/followed when changing to World or More. Root cause: onScreenInit still had a generic fallback placement path whenever the Allow Cheats/Commands anchor was absent.

Fix: the fallback path was removed. The Phayriosis button is now injected only when the actual Allow Cheats / Allow Commands widget exists in the active Create World tab. If that anchor is absent, the handler returns without adding the button. Do not reintroduce a generic fallback position for this button.

No meteor, impact, shockwave, worldgen, entity, or Phase 6 gameplay code changed.
