/**
 * LANE-UI — machine accent colors for build-bar icons.
 *
 * `ItemDef` carries a `color`; `MachineDef` does not, so the build bar has nothing
 * data-driven to tint with. These are transcribed from docs/FKTRY_LORE.md §4 (each
 * machine's ASSET block names its impossible element) as a stopgap.
 *
 * CONTRACT REQUEST filed in NOTES: add `MachineDef.color` — LANE-RENDER needs the same
 * value for its placeholder box tint, and two lanes hand-maintaining the same table is
 * how the build bar and the world end up disagreeing about what a quantizer looks like.
 * Until then: id override, else kind fallback, else house green. Never crashes on a
 * machine we've never heard of.
