Vyāsa supports four ways to configure your blog (in priority order):

1. cli arguments (e.g. vyasa /path/to/markdown) - Highest priority
2. .vyasa configuration file (TOML format)
3. Environment variables - Fallback
4. Default values - Final fallback

Theme presets are bundled with the package, so theme_preset = "ultra-soft" works in normal pip install vyasa deployments without copying a local .vyasa-themes folder. Local .vyasa-themes/<name>.toml files still override bundled presets when present.
