  button "Forgot Password?" -> reset_password()

attempt_login(creds):
  # Validate all fields are present
  if not creds.email or not creds.password:
    show "Please fill in all fields"
    return

  # In real app, this would call an API
  show "Logging in as {creds.email}..."

  # Simulate API call
  success = true

  if success:
    show "Login successful!"
    if creds.remember:
      show "You will be remembered"

  show "Password reset link sent to {email}"

# Form automatically handles:
# - Validation before submission
# - Disabled submit button if invalid
# - Error messages next to fields
# - Loading states during async operations
