World 002 · PlayableThe Paper Owner
A documentary time machine: 94 years of who owns the doctor, with color arriving as you scroll. The circus dentist in 1932 sepia, the rollup boom on 1990s Kodachrome, the venture-backed friendly PC in golden-hour digital, the $100,000 personal fine in crisp 2026 photojournalism.

If a number appears in a world, its § reference is on the page. New worlds drop in the Stream first.
