nothing astounding but
i hand-coded a svg version of the intersex inclusive progress pride flag, as a banner in an aspect ratio suitable for an 88x31 button
it weighs only 850 bytes, or 328 bytes gzipped
that's without aggressive compression: the path instructions are integer-valued, space separated, fairly readable, all the colors use html names not hex codes
9.3k .png here; i'll post a link to the tiny svg when i get my webserver back up tomorrow (whoopsie)
