Reward doing more habits in a single day: the Nth habit checked in a day reveals N units of pixels (1+2+3+... = triangular). Derive revealed pixels from the log per-day triangular sum instead of a flat checks counter; recalibrate pixelsPerCheck so a perfect month still finishes an image. Update DESIGN.md, README.md, ARCHITECTURE.md.
