/**
 * LANE-UI — machine accent colors for build-bar icons.
 *
 * `MachineDef.color` (contracts v2) is the source of truth and wins whenever LANE-DATA
 * has filled it — the same value LANE-RENDER tints its placeholder boxes with, so the
 * bar and the world agree about what a quantizer looks like.
 *
 * The tables below are the round-1 stopgap, kept as fallback: transcribed from
 * docs/FKTRY_LORE.md §4 (each machine's ASSET block names its impossible element).
 * Order: data color, else id override, else kind fallback, else house green. Never
 * crashes on a machine we've never heard of.
