0.3.8f test: same real orthographic 3D camera as 0.3.8e, with expanded vertical pitch range for deeper under-structure inspection. VIEW horizontal drag controls yaw; vertical drag controls true pitch. BUILD geometry and snap rules are unchanged. preserves confirmed 0.3.7n and adds screen-space snap competition for ceilings. Wall Top/Bottom and Ceiling Edge remain legal targets; finger proximity chooses intent, with a small tie margin protecting Ceiling → Ceiling continuation in crowded structures.
