// ── The chat-title conditions (PLAN_REDESIGNS §5, D172–D175, D209) ─────────
//
// Four things here, each a mistake that would look right in review:
//
//   • **a best is not a sum.** The two distance columns take GREATEST at ingest;
//     adding two intervals' maxima would give a kill nobody made.
//   • **"NPC kills" subtracts in SIGNED arithmetic.** `npc_kills` is unsigned,
//     and a row counted before `animal_kills` existed must not wrap to 4 billion.
//   • **a rename reaches a rule with no text.** The rule's own text wins, then
//     the admin's category title, then the default (§4.6's three layers).
//   • **a category's title is never a rule's text by accident.** An empty text is
//     "use the category's", and a typed title made of markup is still refused.
