1. Create a branch from main.
2. Make focused, minimal changes.
3. Run relevant checks locally.
4. Open a pull request with clear context.

• Keep PRs scoped to one topic.
• Include a short summary of what changed and why.
• Reference related issues when applicable.
• Update docs when behavior changes.

• Follow existing project style and conventions.
• Avoid unrelated refactors.
• Prefer clear, maintainable implementations.

Use concise, descriptive commit messages (for example: feat: add airport search index).
