Verified the parser captures a straddle from every non-blind seat (UTG..BTN, 7/7),
so no behavior change — but the prompt only named UTG/button examples. Spell out
that a straddle is legal from ANY non-blind seat (Mississippi/any-seat straddle,
common at the Meadows) and state the open-action seat per straddle position, as
insurance against model drift.
