Persona templates

Five built-in templates are available: xuwen (default), friend, lover, family and colleague. Select one in .env:

PERSONA_TEMPLATE=lover

For a custom template:

PROMPT_TEMPLATE_DIR=/path/to/your/templates
PERSONA_TEMPLATE=my_template
# Reads /path/to/your/templates/my_template.md.j2

Available variables: friend_name, self_name, relationship_description, persona_card, retrieved_friend_examples, retrieved_dialogue_windows, recent_conversation, current_user_message, today, current_date, current_time, current_datetime, current_weekday and timezone. retrieved_friend_examples prioritizes response-pair examples. Treat persona_card as long-term style guidance, not evidence of today's facts.

Internal built-in instructions use English with output-language rules. Your custom template is preserved as written; keep its output-language policy explicit if you use multiple languages.
