POST /api/public/chat proxies to OpenRouter (model from
OPENROUTER_MODEL, default deepseek/deepseek-v4-flash:nitro) with a
system prompt built from live site config, sponsor queue, and strict
guardrails (no income claims, seed-phrase warnings, Telegram fallback).
Rate-limited per IP. Without OPENROUTER_API_KEY set, or on any API
error, the widget transparently falls back to the built-in knowledge
base, so the chat always works.
