Architectural and cross-package changes — dependency direction, editor/runtime boundaries, scene schema, persistence, renderer packages. Use when changing package boundaries, serialized formats, or multiple layers. Do not apply to localized UI, styling, or test-only edits.

Vitest conventions for domain, commands, server, and security tests. Apply when editing .test.ts / .test.tsx / spec files.

TypeScript conventions for this monorepo (strict mode, Zod boundaries, package imports, naming). Apply when editing .ts/.tsx files.
