Ensure configuration handling is consistent and platform-agnostic by following these guidelines:

1. Use environment variables with fallbacks: ```rust // Good let sample_count = std::env::var(“ZED_SAMPLE_COUNT”) .or_else(|_| std::env::var(“ZED_PATH_SAMPLE_COUNT”)) .unwrap_or_default();

// Bad let sample_count = std::env::var(“ZED_SAMPLE_COUNT”).unwrap_or_default();

2. Implement proper default values using serde attributes:
```rust
#[derive(Deserialize)]
pub struct Config {
    #[serde(default = "default_true")]
    pub enabled: bool,
    
    #[serde(default)]
    pub custom_path: String,
}

1. Use platform-agnostic paths and commands: ```rust // Good let config_dir = dirs::config_dir() .or_else(|| std::env::var_os(“XDG_CONFIG_HOME”) .map(PathBuf::from));

// Bad let config_dir = PathBuf::from(“/usr/local/etc”); ```

1. Provide clear validation for configuration:
   • Validate all required fields
   • Include schema documentation
   • Support cross-platform paths
   • Handle missing values gracefully
2. Allow configuration overrides through multiple layers:
   • Environment variables
   • User configuration files
   • System defaults
   • Platform-specific defaults

This ensures configurations work consistently across different platforms while maintaining flexibility and robustness.
