Mimir build and both Fensalir field evidence smokes pass; remaining cuts are per-pixel source-row material sampling, ramp texture binding/fallback, indirect draw packets, and non-buffer resolvers."}

Initial material is opaque field geometry with fallback black-to-warm ramp, squared normalized emission, and fake Fresnel center-bright/edge-dark shaping. Real blackbody ramp texture binding, indirect draw packets, and non-buffer resolvers remain future cuts.

The field DSL accepts `texture2d id=... key=... path=...`, TubeField `ramp=...` resolves aliases to resource keys, D3D12 lazily uploads local Rgba8 assets and binds the ramp SRV with linear clamp sampling, and unresolved ramps use a Fensalir-owned 0-1 fallback texture.
