⚙️ Behavior & Mechanics

Surface (Y > 16): Sections 0–3 are emptied, block entities below Y < 0 are stripped, and entities below Y < 0 are hidden.

Underground descent (Y <= 16): Everything is revealed immediately using batched, nearest-first chunk resends.

Ascent (Y >= 20): Culled again, but only after the safety cooldown period (default: 3000 ms).

Deep Underground (Y <= 0): Send/view distance is locked to 6 chunks.

Returning upward (Y >= 10): Send/view distance is restored to server default (-1) after the cooldown expires.
