f365.format, locale-aware formatting

Format dates, currencies, numbers, and file sizes using the user's locale, backed by Intl, no third-party library.

The f365.format namespace wraps the Intl APIs with a tighter signature than the platform exposes. Locale defaults to

navigator.language; override per call when you need a fixed format.

  if (file) f365.field('AttachmentSize').value = f365.format.bytes(file.size);
});
