Guidelines for using window.alert() and window.confirm() in web applications. Use when implementing error notifications or destructive action confirmations.

Do not disable GHC or hlint warnings. Suppress them only per module with OPTIONS_GHC or annotations for justified exceptions. Use when writing or reviewing Haskell code, cabal files, or hlint configuration that disables warnings.
