Why unicode blocks?

Dot/ASCII QR renders use low-contrast characters that phone cameras — especially in dark terminals — struggle to lock onto. stabiron uses half-block characters so each QR module is a solid rectangular region of colour, doubling vertical resolution and maximising contrast. The result is near-instant scans even on a first-gen iPhone SE.

Error correction

All QR codes are generated at HIGH (H) error correction level (30% damage recovery). This compensates for terminal font imperfections and anti-aliasing artefacts when a phone camera captures the screen.
