class_name Races
extends RefCounted
## The 4 races (races-and-classes spec §3). FEATURES ONLY — no race touches an
## attribute score, which is what keeps the roll + spend pure.
##
## nightsight / claws / keen_scent are FLAGS, not numbers. Combat (M5) and the DM's
## exploration checks consume them; creation only stores them.
##
## The dwarf's +2 is SITUATIONAL (vs poison and the affliction track), so it is NOT
## a flat save bonus — baking a conditional into a flat number is how a sheet starts
## lying. It is exposed separately as poison_save_bonus().
