// AoC 2015 Day 14 Part 1 — reindeer race, max distance at t=1000
// (statement: Comet 1120, Dancer 1056 → 1120). PURE .k since 2026-06-12:
// parse-reindeer retired by regex NAMED GROUPS — the sentence form IS the
// pattern, three typed fields convert at the splice, and the distance
// formula stays where it always was: Koru expressions. Ledger is empty.
