 * A fixed station of the carrier (DESIGN_UE.md section 3.4): helm, chart table, beds, nutrient ports, vat, packer, storage wall,
 * Tethys terminal, carousel console, pool ladder. Not placeable. The actor is attached to the carrier, owns the blockout visual and
 * collision of the station (built from FCarrierLayout's anchor, so real models replace it later) and is an IDescentInteractable.
 * A station that is not built yet shows its prompt and answers E with a toast naming the milestone that gives it its function;
 * the carousel console and the pool ladder work since M3.
