Real-time validation (don’t nag)

This micro-demo compares naggy validation (error flashes while you’re still typing) vs polite validation (waits until blur or after a short pause). Try typing alex@example.com.

BEFORE: naggy

Enter a valid email address.
This updates on every keystroke, even mid-typing.

AFTER: polite

No message yet.
Only shows an error after you leave the field, or after a brief pause.
Why it matters (quick note)

Rapidly changing error messages can be distracting, and for some assistive tech users it can create repeated announcements. A common pattern is: validate on blur, or validate after a short debounce (and don’t mark the field invalid until the user is done typing).
