FuguSeed

Make BIP39 seed words with three dice on paper, and turn them into a SeedQR. fuguseed-words builds and checks a printed word sheet. On that sheet, one throw of a d8 and two d16 selects one of the 2048 words, with no arithmetic. Its manual holds the offline procedure. fuguseed-qr turns the 12 words into a Standard SeedQR, zone by zone, in a terminal.

The two programs have two trust levels. fuguseed-words sees no seed word, so it can run on any computer. It builds on the Fugu library. fuguseed-qr sees the words, so it must run on an air-gapped computer only. It is one packed file on core Perl v5.34, with no dependency. FuguSeed is a companion of FuguPass: it makes the master that FuguPass reads. The specification in spec/ states the design.
