Documented products, not rankings

Choose the camera. Then the slot.

These selected camera profiles document card-slot families. Recording modes, approved cards and firmware need separate checks.

Read the scope, not just the badge.

Documented family, explicit exclusion and missing documentation are different states. A product absent from this directory has not been evaluated here.
