## 2024-05-22 - Missing Scripts and Environment
**Learning:** The project lacks `lint` script in `package.json`. Running `pnpm lint` might invoke system tools (like Android Lint?) instead of failing or doing nothing useful. Always check `package.json` scripts first.
**Action:** Use specific commands like `pnpm exec tsc --noEmit` or `npx vitest` as discovered/documented, rather than assuming standard scripts exist.

## 2025-01-26 - Missing Node Modules
**Learning:** The environment might lack `node_modules` completely, preventing `npx vitest` or `pnpm exec tsc` from running even if dependencies are listed in `package.json`. Network restrictions may prevent `pnpm install`.
**Action:** When `node_modules` is missing and cannot be installed, rely on static analysis, careful code review, and verifying file contents manually. Do not assume tests can run.
## 2024-05-22 - High-Frequency State Isolation
**Learning:** High-frequency state updates (like typing effects) in large parent components (`Hero`) trigger massive unnecessary re-renders of expensive sub-trees (`GradientBlinds`, `Button`).
**Action:** Isolate high-frequency state into small, leaf-node components (e.g., `TypedText`) and wrap them in `React.memo` if necessary, keeping the heavy parent static.
