Stacks & display

Stack geometry (SPR, effective stacks, big-blind sizing), human-readable pot odds, tournament M and Q, orbit cost, minimum raise sizing, and preflop combo counting. Chip-share normalization here is not Harville ICM—that lives under ICM.

Use these exports for HUD labels, stack-depth displays (Harrington M / Q), and preflop combo counts where you need fast display helpers without running a full sim.
