-- Tariff-lab drafts (2026-07-05). A mutable scratchpad for the lab: the admin composes
-- experimental rate cards here, simulates them against hypothetical stays, and only
-- PUBLISHES (normal immutable tariff_versions path) when satisfied. Deliberately mutable —
-- a draft prices nothing and signs nothing; experimenting through real publishes would
-- churn permanent versions and risk a wrong card going live. See wiki/concepts/tariff.md.
