Usage notes:
- Base64 is encoding, not encryption.
- Browser-local processing reduces server submission but does not make sensitive input absolutely safe.
- Calculator, converter, date, commerce, SEO, and security utilities are practical aids, not professional advice or compliance decisions.
- Planned locale paths are not published until their locale is active.
