## The tribe roster data that drives a LOCAL tribe-vs-tribe match: `AbilityData.TRIBE`
## records which heroes form which tribe, `tribe_of` maps a hero back to its tribe, and
## `opposing_tribe` names the side it is matched against. `main._start_local` composes
## these to seat the player's chosen tribe against the opposing one — so `--hero snake`
## now fields the Verdani for the player. Pure data, checked without a live client.
