Square Zero: hide silly messages in decorative borders

I’ve seen this embedded within geographic paths that form polygons. There are many points along each side of a polygon, arranged so that each segment length is longer (1) or shorter (0) than the one before. Decrypts to two floats, offsets from the first point.

I'm confused by the card "hope you soar in 2024". This card was mailed this year? I don't understand the footnote about 2/19. Was it sent in February 2024 and just posted about now?

I prefer the codes of Chris Seivey/ Frank Sidebottom.

Only, it too GCHQ to finally solve them.

I used to do this when I designed rave flyers in the 1990s.
