<AccordionGroup>
  <Accordion title="What happens if I try to remove the last owner?">
    This isn't allowed — every outlet needs at least one Owner-level user at all times.
  </Accordion>

  <Accordion title="Can I create a role with zero permissions?">
    No — every role must have at least one permission assigned.
  </Accordion>

  <Accordion title="What if I edit a role that's assigned to several people?">
    The change affects every user with that role, not just one.
  </Accordion>

  <Accordion title="What if two outlets try to use the same phone number?">
    You'll see an error: the number already exists on another outlet.
  </Accordion>

  <Accordion title="What if my fallback number is missing?">
    Calls that would otherwise be forwarded may drop instead.
  </Accordion>

  <Accordion title="My outlet was active, but became inactive later — what happens?">
    If a subscription expires, the existing number becomes inactive, but call forwarding can remain on — which leads to a broken experience for callers until you address both.
