/* ============================================================================
   RRFlows token contract. Canonical shape for ALL NEW work.
   Authored 2026-08-04. Binds new products only; existing products are frozen
   legacy (see _contract/README.md for which product uses which convention).

   This file is the contract. Prose describing it is a summary, not the source.
   A brand bundle overrides the VALUES in the :root / theme blocks and keeps
   every SLOT NAME identical. Never rename a slot per client.

   Theme rule, added because a controlled A/B test on 2026-08-04 found that a
   hardcoded dark palette caused 3/3 agent builds to ship dark-only where 3/3
   control builds shipped both. Light is the default; dark arrives via the OS
   preference AND an explicit [data-theme] attribute so a UI toggle can win.
