Backend:
- Channel/initiation now driven by a SCENARIO chosen at chat start, not baked into the
persona: social (customer opens), f2f_call (seller must open, proactive), recontact
(customer re-contacts after 1-3 months).
- /chat/start accepts {scenario}; session stores scenario + internal{turns,score}.
- persona_reply takes scenario + adapts tone; system-role transcript entries are fed to
the persona as hidden scene notes.
- JUDGE updated for realism: good response can WIN even in hard/tough-text scenarios;
long/no-close chats (turns >~12) lose; pushy/ignoring-need loses. Efficiency rewarded.
Frontend:
- Scenario picker before chat (choose Social / Face-to-face-call / Re-contact).
- Chat thread renders role=system as a centered time-lapse/scene note.
- Choose-scenario i18n (EN+TH).
Rebuilt dist.
