"""
Generate numbered QR PNGs from an existing base64 file (single line or multi-line).

Workflow (you already have the .b64):
  1) This script reads the .b64 text, strips ALL whitespace (handles Qrox+ newline/space behavior too),
  2) Splits into chunks (default 2000 chars total payload INCLUDING header),
  3) Prefixes each chunk with a fixed header: ###0000### (10 chars),
  4) Generates QR images (Version 40, Error L) with screen→phone friendly sizing.
