BlockEffect

New content

• Course border wand — creative tool to trace a flight path and spawn an invisible course border fall block wall along it (±30 blocks tall per column).
• Course border fall block — invisible fall block for out-of-bounds walls; shows a proximity hint when you are nearby. Uses the same checkpoint teleport logic as the regular fall block.
• Fan block — directional wind that pushes entities along its facing. Configurable wind strength (−1 repulsion → +1 attraction) and range (2–16) via the Block Effect Modifier. Cloud particles flow toward the fan.
• Kinetic platform — 3×1×3 moving platform (controller + slabs). Pick with the modifier, shift+right-click a destination center, set speed and smooth round-trip in the GUI, then activate on close. Walkable collision; shift+right-click while moving to stop and place blocks back.

Fixes & polish

• Kinetic platform visuals render in world space with stable client interpolation (fixes strobing/flickering while moving).
• Fan inventory preview renders as a full cube (BEWLR).
• Propeller removed from the creative tab (still exists for existing maps).
• Void Hub “not a void hub world” log spam reduced to a single debug message.
