## Common Violations
### Loading State Flicker
```tsx
// ❌ Bad: Flickers on fast responses
const [loading, setLoading] = useState(false)
async function handleClick() {
setLoading(true)
await action()
setLoading(false)
}
// ✅ Good: Minimum visibility time
async function handleClick() {
setLoading(true)
const start = Date.now()
await action()
const elapsed = Date.now() - start
if (elapsed < 300) {
await new Promise(r => setTimeout(r, 300 - elapsed))
}
setLoading(false)
}
/* ❌ Bad: Animates everything, causes jank */
.button {
transition: all 0.2s ease;
}
/* ✅ Good: Specific properties */
.button {
transition: background-color 0.2s ease, transform 0.2s ease;
}
/* ❌ Bad: No reduced motion support */
.slide-in {
animation: slide 300ms ease-out;
}
/* ✅ Good: Respects user preference */
.slide-in {
animation: slide 300ms ease-out;
}
@media (prefers-reduced-motion: reduce) {
.slide-in {
animation: none;
}
}
// ❌ Bad: Doesn't help user fix it
<span className="error">Invalid input</span>
// ✅ Good: Shows how to fix
<span className="error">
Email must include @ symbol (e.g., name@example.com)
</span>
// ❌ Bad: 16px icon, 16px hitbox
<button className="p-0">
<CloseIcon className="w-4 h-4" />
</button>
// ✅ Good: 16px icon, 44px+ hitbox
<button className="p-3">
<CloseIcon className="w-4 h-4" />
