Making notes
Design, code and writing were prepared for this edition with AI assistance. Experiments run in the browser; reading the pages does not require JavaScript. A reduced-motion preference starts BAŞKA paused. TRACE only recomputes when you change a setting.
World names are metaphors. The patterns are not presented as living organisms or as models of actual ecosystems. Research drafts identify their completion status on their own pages.
