+/**
+ * Frank, Habbo's mascot. Behaves as a Butler (inherits the give-item
+ * walk-and-serve flow from ButlerBot via bot_serves) plus a keyword
+ * to chat-reply layer for the non-item conversational commands
+ * ("cat", "Vietnam", "Miranda", "help", "Frank Black", "life",
+ * etc).
+ *
+ * Chat replies live in `bot_chat_responses` keyed by bot_type so
+ * other future scripted bots can reuse the same table. Each row's
+ * `keys` is a semicolon-separated list of trigger words, `responses`
+ * is a newline-separated list of replies that Frank picks from at
+ * random for variety.
+ *
+ * Resolution order on each user message: chat reply first (instant,
+ * no walking) - if no chat keyword hits, fall through to the
+ * inherited ButlerBot logic so item commands keep working.
