JS Safe Mode (conservative):
Conservative minification. Removes comments, blank lines and edge whitespace without touching strings, template literals or regex literals.
Keep /*! license comments:
Preserves only /*! … */ comments, e.g. MIT/GPL notices. Removes other block comments.
Remove // line comments:
Removes real // comments with a scanner; preserves http(s)://, data:// and //# sourceMappingURL.
Recommendation:
Keep all three options enabled for safe and effective minification.
