## 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.
## 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.

## 2025-02-18 - Missing Alerts for Dynamic Status
**Learning:** The application uses `framer-motion` for dynamic feedback messages but consistently lacks `role="alert"` and `aria-live` attributes, causing screen readers to miss critical status updates.
**Action:** When auditing forms, check all `motion.div/p` elements used for feedback and add `role="alert"` and `aria-live="polite"` (or "assertive" for errors).
## 2024-05-22 - Semantic Required Fields with Custom Validation
**Learning:** To combine custom validation UI with semantic `required` attributes (vital for a11y), add `noValidate` to the `<form>`. This prevents native browser bubbles while keeping the accessibility benefits.
**Action:** Use `noValidate` on forms when implementing custom validation but keep `required` attributes on inputs.
