Enum Feature 

#[non_exhaustive]
pub enum Feature {
    Capture,
    SkyPanorama,
    CarveActiveSprite,
    TranslucentSpriteMaterials,
    TranslucentTerrain,
    FreePickDepth,
}

A backend-dependent capability, probed via SceneRenderer::supports (QE.7a). Every method below the parity line degrades to a silent no-op on the unsupporting backend; this enum turns the tribal knowledge into a queryable answer.

Feature	CPU	GPU
Capture	✅	✅ native (❌ wasm — WebGPU can’t block)
SkyPanorama	❌ (use FrameParams::sky)	✅
CarveActiveSprite	❌	✅
TranslucentSpriteMaterials	✅	✅ (TV.3)
TranslucentTerrain	✅	✅ (TV.6)
FreePickDepth	✅	❌ (blocking readback)

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Capture

SceneRenderer::request_capture / take_capture produce frames.

SkyPanorama

SceneRenderer::set_sky_panorama uploads a sampled sky (the CPU backend samples FrameParams::sky instead).

CarveActiveSprite

SceneRenderer::carve_active_sprite carves.

TranslucentSpriteMaterials

Per-voxel / per-instance sprite materials composite translucently (an unsupporting backend renders them opaque).

TranslucentTerrain

SceneRenderer::set_terrain_materials terrain translucency composites (an unsupporting backend renders terrain opaque).

FreePickDepth

SceneRenderer::pick_depth is cheap enough for per-frame use (an in-memory read). Unsupporting = it works but blocks on a device readback — hotkey-grade, not reticle-grade.
