/* /own-your-intelligence (30 Oct 2026): the instrument is a seal of ownership (own-your-intelligence.aspx.vb):
   the core inside three rings (memory, rules, learning) and interchangeable engines outside that take turns
   connecting to it, over a panel that plays each chapter's scene. Shown by the run (sub.js) from .oi[data-st].
   Ambient motion: the engines take turns (the models change, the core does not). Reduced motion shows one engine
   connected and every scene at rest. Light and the one orange accent; tokens only. */
