 ## Prerequisites and Setup
 
-- **Node.js**: `>=24` (`.nvmrc` pins `24.18.0`). Use `nvm use` to activate the right version.
-- **Install pnpm globally**: `npm install -g pnpm`
+- **Development tools**: Install [mise](https://mise.jdx.dev/), then run `mise install` to activate the Node.js and pnpm versions pinned in `mise.toml`.
 - **Bootstrap the repository**: `pnpm install` — takes up to a minute on a clean install. NEVER CANCEL. Set timeout to 5+ minutes.

 ## Development Workflow

+- **Full build**: `pnpm build` — builds all targets via Vite. Output goes to `build/` (subdirectories: `main/`, `preload/`, `renderer/`, `shared/`).
 - **Run the Electron app**: `pnpm start` — runs `pnpm build` then `pnpm dev`. Will fail in headless/container environments due to Electron sandbox restrictions (this is expected and normal).

 ## Constraints and Gotchas
 
 - **Electron won't start in CI/containers**: Sandbox restrictions make `pnpm start` / `pnpm dev` fail headlessly. This is expected — test logic; don't try to fix the launch.
-- **Node version is strict**: `>=24` required. Check `.nvmrc` and run `nvm use` if commands behave oddly.
+- **Node version is strict**: `>=24` required. Run `mise install` if commands use the wrong Node.js or pnpm version.
 - **Snapshot drift on non-UTC machines**: Some snapshot tests encode relative dates. Tests may fail locally if your timezone differs from UTC. The test setup stubs `TZ=UTC` via `vi.stubEnv`.
 - **Lint warnings are OK**: The codebase has pre-existing lint warnings. Only new errors block CI.
 - **GraphQL codegen**: Running `pnpm dev` auto-watches for schema changes. If you edit `.graphql` files manually, re-run `pnpm codegen` to regenerate `graphql/generated/graphql.ts`.
