1//! Relationship familiarity: a light, prompt-level sense of how well the bot
2//! "knows" the person it's talking to, derived from how much history they share
3//! (the stored message count). People treat a stranger and an old friend
4//! differently; this nudges tone the same way.
5//!
6//! Conservative by design: only the extremes (brand-new vs. long-time) inject
7//! anything. The broad middle stays silent so we don't over-prompt.

15/// broad middle where no nudge is warranted.
