Historical Flags & Predecessor Standards
In FastFlags, historical flags receive standalone profiles only when they document a foundational design lineage or statutory geometry change—such as the 1572 Dutch Prinsenvlag that launched the European tricolor tradition or Japan's 1870 merchant specification superseded by the 1999 Flag Act.
