Magnet Hopper

A hopper variant that pulls dropped items in a 3D radius before depositing them into the container below. Solves the universal "items despawn around my mob farm" pain in one dedicated block.

Features

Magnet pull — ItemEntities in the tier's 3D radius get vacuumed into the internal 5-slot storage and flow down into the container below.
Vanilla hopper behavior always active — strict superset of a regular hopper: pulls from any container above, pushes to any container below at the standard 8-tick cadence.
Magnet on/off toggle — UI button to disable just the magnet pull (block keeps acting as a normal hopper).
5-slot whitelist/blacklist filter — click a filter slot with an item to ghost-set (the item isn't consumed); empty-hand click to clear; toggle whitelist/blacklist in the UI.
Redstone-disable — applying a redstone signal pauses everything (matches vanilla hopper convention).
Placement preview — hold a magnet hopper in either hand and the affected radius draws as a cyan-mint wireframe over your cursor target, with a warm-green surface contour that follows terrain so the floor coverage is always legible.
Pipe compatibility — exposes the 5-slot storage via Fabric ItemStorage.SIDED and the NeoForge item-handler capability. Filter slots are config, not exposed.
