[Set up in IntelliJ](https://docs.github.com/en/copilot/how-tos/configure-custom-instructions-in-your-ide/add-repository-instructions-in-your-ide?tool=jetbrains) using the manual setup guide, not a one-click installer. Use the repository-wide \`.github/copilot-instructions.md\` workflow above. The resource's \`applyTo\` patterns are not enforced in this file, so include only guidance appropriate for the whole repository.`,
