Local Development

To test features locally in VS Code:

1. The Dev Containers CLI requires local features to live under .devcontainer/.
2. Copy or sync the feature into .devcontainer/<feature-name> (for example .devcontainer/oh-my-posh-theme).
3. Add the feature to .devcontainer/devcontainer.json using a relative path like "./oh-my-posh-theme": {}.
4. Rebuild your dev container.

If you want to keep src/ as the source of truth, add a small sync step that mirrors src/<feature-name> into .devcontainer/<feature-name> before rebuilding.

Publishing

Features are automatically published to OCI registry when releases are created.
