// Setting a building up when it starts existing or is reconfigured: sizing its
// input/output buffers from what it will produce, and handing belt-like types back
// to BeltSystem. Free functions over the config and the building — they read no
// factory state, so both BuildingSystem and ConstructionSystem can use them.

// Buffers for a building running one known recipe: one buffer per material on each
// side, capped at twice that material's per-cycle amount (REQ-MAT-INPUT-BUFFER,
// REQ-MAT-OUTPUT-BUFFER).

// Registers a belt, splitter or tunnel end with BeltSystem. A splitter's filters
// live in BeltSystem and are lost by removeTile, so they are passed back in
// (REQ-BLD-SPLITTER). No-op for every other building type.
