Error correction
Error correction trades capacity for damage tolerance. The encoder upgrades to the strongest level that still fits the same code size (an arrow on the badge means you got it for free). Pick H only for small prints, curved surfaces or a logo on top. Quiet zone is the white margin; scanners want 4 modules. PNG exports stop at 4096 px a side; use SVG for print.
