Own the Void – a trillion-cell infinite canvas
This is an engineering-first take on the million-pixel idea: a 1,000,000×1,000,000 logical grid where only claimed cells hit storage and the client pulls tile-based viewport queries while a DPR-aware Canvas draws without full redraws. The clever parts are the sparse-storage model and edge serving via Cloudflare Workers+D1, but the product hinges on hard questions — D1 query scaling, cheap moderation for free text, and whether a €1-per-cell economy actually funds permanent storage.
