Style Support Matrix

forge3d style support is scoped to local/provided features. It is not streamed MVT rendering and it is not complete Mapbox style parity.

Capability	Support level	Scope	Diagnostics
fill layers	supported	Local/provided polygon features with fill-color, fill-opacity, and fill-outline-color.	unsupported_style_field for unsupported paint/layout fields.
line layers	supported	Local/provided line features with line-color, line-width, and line-opacity.	unsupported_style_field for unsupported paint/layout fields.
circle layers	supported	Local/provided point features with circle-color, circle-radius, and circle-opacity.	unsupported_style_field for unsupported paint/layout fields.
symbol text layers	underdeveloped	Existing style-to-label helpers can preserve some text styling, and production LabelPlan / LabelLayer workflows are validated through MapScene.validate.	experimental_feature, missing_glyphs, or label_rejection_summary diagnostics when used in production workflows.
Other style layer types	unsupported	Heatmap, raster, hillshade, fill-extrusion, background, and other layer types are outside the P0 local-feature subset.	unsupported_style_layer_type.
Streamed vector tiles	non-goal	Hosted/live tile delivery is outside this feature.	Documentation boundary, not a render path.

Unsupported style fields must be reported before render; they must not be silently dropped in PRD-scoped workflows.
