|--------------------------------------------------------------------------
| Abilities are gated by capability as well as permission
|--------------------------------------------------------------------------
|
| Two independent gates: a permission says what a role may do, a capability
| says what the edition has at all. Every other surface applies both
| (routes/web.php pairs `capability:users.manage` with `can:manage_users`;
| the sidebar pairs them again). Token issuance must too, or a cloud install
| offers abilities for features it does not have.
|
| The suite runs as community by default (phpunit.xml), which is why the
| original permission-only implementation looked correct here while the
| cloud dev install visibly offered custom-asset and user-management
| abilities that could never work. These flip the edition explicitly.
