game/archetypes.py

"""Pre-baked personality archetypes. Picked at random when a character
spawns; the user can edit any personality at any time from the side panel.

The set is hand-tuned to be theatrically diverse — pairs of archetypes
should produce friction or alliance, not blend into one sound. Each is
written in second person ("You are…") so it can be concatenated after
THE_DOT and read smoothly.

Each archetype carries a `reward` line — what gives this character joy or
satisfaction. Small models follow goals more reliably when an emotional
hook is explicit, so we surface the reward in the system prompt.
