WARN crates/bevy_shader/src/shader_cache.rs:297 Shader `shaders/custom_material.wesl` has an unresolved import:error: module not found: `package::shaders::custom_material_import` (no shader registered for this module path)  |  = note: in package::shaders::custom_material (shaders/custom_material.wesl)

Rendering works and custom_material_import.wesl is loaded correctly, but bevy attempts to load COLOR_MULTIPLIER.wesl, but it's a declaration, not a file.
