csb

Generate streaming, Excel-friendly CSV downloads in Rails with the csb gem. Use when implementing a CSV export/download, writing a `.csv.csb` template, building CSV via Csb::Builder, or testing column definitions. Not for parsing CSV.

Maintain the Ruby and Rails version matrix tested in CI for a Ruby gem. Use this when you need to remove EOL versions, add the latest supported versions, and update gemfiles and gemspec accordingly. Always use this for requests like 'remove unsupported Ruby/Rails versions', 'add the latest Rails', or 'update the CI matrix'.
