Detailed Description

QR encoding into a packed 1-bpp raster via espressif/qrcode.

The qrcode display callback carries no usable user_data round-trip, so a file-static context struct holds the target buffer (the QRCodeView pattern). A static mutex serialises concurrent callers - plugin WASM frames can run on more than one task.
