TIL we possibly should be using an ifdef for the webgl2 padding here:

bevy wgsl example

struct PostProcessSettings {
    intensity: f32,
#ifdef SIXTEEN_BYTE_ALIGNMENT
    // WebGL2 structs must be 16 byte aligned.
    _webgl2_padding: vec3<f32>
#endif
}

bevy rust example

struct PostProcessSettings {
    intensity: f32,
    // WebGL2 structs must be 16 byte aligned.
    #[cfg(feature = "webgl2")]
    _webgl2_padding: Vec3,
}
