JS Safe Mode (conservative):
Conservative minification. Removes extra spaces/newlines and comments without risky syntax changes.
Keep /*! license comments:
Preserves only /*! … */ comments (e.g., MIT/GPL notices). Removes other block comments.
Remove // line comments (heuristic):
Safely removes // comments; automatically ignores http(s)://, data:// and //# sourceMappingURL.
Recommendation:
Keep all three options enabled for safe and effective minification.
