            Your PR title \`${title}\` doesn't follow our conventional commit format.

            Please update it to start with one of these prefixes:
            - \`feat:\` new feature or functionality
            - \`fix:\` bug fix
            - \`docs:\` documentation or README changes
            - \`chore:\` maintenance tasks, dependency updates, etc.
            - \`refactor:\` code refactoring without changing behavior
            - \`test:\` adding or updating tests

            **Examples:**
            - \`docs: update contributing guidelines\`
            - \`fix: resolve crash on startup\`
            - \`feat: add dark mode support\`

            See [CONTRIBUTING.md](../blob/dev/CONTRIBUTING.md#pr-titles) for more details.`;
