- Convert tabs to spaces (3,413 violations)
- Fix line endings, trailing whitespace, brace placement
- Break lines exceeding 150-char absolute limit
- Replace heredoc tab closers with spaces
- Fix empty elseif, forbidden function calls
- Update phpcs.xml: exclude rules inappropriate for CLI scripts
