ever-works

Repo-specific guide to the Ever Works monorepo (ever-works/ever-works) — its pnpm + Turborepo layout, the per-workspace test runners (Jest vs Vitest vs Playwright), file-naming and import-alias conventions, the commit/branch model, and the real build/lint/type-check commands. Use this whenever working anywhere in this repository so changes match the codebase's actual conventions and pass CI.
