Gemfile:6

• The Base64 module is part of Ruby’s standard library, so explicitly adding it as a dependency may be unnecessary and might introduce versioning conflicts; consider removing it if not required.

gem 'base64'

• [nitpick] The change from 'MiniTest::Spec' to 'Minitest::Spec' may cause inconsistencies if other parts of the codebase still refer to the original name; please ensure that all references are updated consistently.
