{# Is the viewer OUR staff? Drives the internal-only chrome on this page: the
   "comments are visible to everyone" warning and the per-comment
   "Customer visible" / "Staff only" badges. Both are instructions about how WE
   work and must never reach a customer account.

   Written as an explicit ALLOWLIST of our own roles, deliberately:

   * It FAILS CLOSED. The obvious form, `not current_user.is_customer_account`,
     fails OPEN — if the attribute is missing for any reason (a process still
     running an older models/user.py after a template-only reload, say) Jinja
     yields Undefined, `not Undefined` is true, and the internal text is shown
     to exactly the people it must be hidden from. An allowlist of literal role
     strings can only ever be true for a role we listed.
   * `external_inspector` is absent ON PURPOSE. This is NOT the rule-87 case:
     rule 87 is about capability/scoping, where a Customer Inspector must
     behave exactly like our own inspector. Here the question is "does this
     person work for us?", which is the one place the two genuinely differ.
     Do not "fix" this by adding external_inspector to the list. #}
