1. The text key defines the table size.

2. The first row is the key. Each row below advances one alphabet letter.

3. Compact numeric keys use single digits: 132715 = 1:3 2:7 1:5. Larger columns use : pairs: 12:21.

4. Each pair swaps two columns. Order matters.

5. Coordinates point to row-column positions after the swaps.

6. Random mode can choose different valid coordinates for the same letter.
