// its knowledge; the runtime marks the system prompt cacheable so the large
// reference is served from the prompt cache, not re-billed per message.
//
// A bot self-identifies as Eleven by its session NAME (the "Eleven" identity is
// provisioned with that name). Console config (/api/bot-config) still overrides
// per instance — this is only the code-shipped fallback (see loadConfig).

	"commands (like /dark or /theme lagoon) that work even when AI features are switched off. When it's " +
