SMS opt-in at Albus. This is the exact onboarding screen Albus customers complete after signing in with Google, where they enter their mobile number and agree to receive texts. The consent box starts unchecked, and Albus does not save a number or send a text without it. Published so SMS carriers and reviewers can verify the opt-in experience without an account. The form is in preview mode and does not submit.

Next time, just text it.
