Conservation note

Primary species is native Southern Appalachian Brook Trout (Salvelinus fontinalis, southern lineage / SABT). brook_trout now scores as a char comfort-overlay (char welfare ceiling ~20°C — earliest of the salmonids) once `npm run seed:species` is applied; handled conservation-first. Reopened to fishing in 2015 after a ~7-year non-native removal restoration.
