About FEEN
FEEN (Field Expression Encoding Notation) is a rule-agnostic, canonical position encoding
for two-player, turn-based board games built on the Sashité Game Protocol.
FEEN strings consist of three space-separated fields:
<PIECE-PLACEMENT> (board configuration using EPIN tokens),
<HANDS> (pieces in each player's hand), and
<STYLE–TURN> (styles and active player using SIN tokens).
