⭐ Starforge is alive in the browser! This is day two building a multiplayer pixel art studio. So far the editor opens with a little star, and every pixel stays razor sharp at any zoom. With 37 green tests I already started coding the first drawing tools (pencil, eraser, bucket).

The sharpness comes from a two stage blit with shared memory. A sprite’s pixels live in one Uint8Array wrapped in an ImageData view, using only one buffer for model and image bytes. Stage one pushes just the changed rectangle onto an offscreen canvas (1:1) which ignores scaling and smoothing so it never blurs. Stage two is a single draw image that stretches the offscreen canvas to the current zoom with the GPU doing the nearest-neighbor upscaling for free. When the pencil lands next ship, the bytes it writes are already the bytes the renderer reads.
