#### Appearance

Theme
Light surfaces for daylight reviews; dark for sustained ops.
Density
Affects panel padding and font scale.
Reduce motion
Pauses dashed field-line animation.

#### Simulator

Default seed
ChaCha20 PRNG entropy. Same seed → byte-identical output.
Auto-run on edit
Re-emit frame stream when scene mutates.
Heavy-attenuation flag
Surface conjectural material loss values.

#### Runtime

WASM backend
Compiled with --release; SIMD enabled.
Console verbosity
Witness on every run
SHA-256 frame-stream digest written to ./proof/.
