/* demos.css — the shared kit for the four interactive proof demos
   (generic-vs-OS on /brand-os/, conflicting sources on /method/guardrails/,
   the live-data loop on /company-os/, the pricing engine on /work/).
   One file so the four read as one system. Everything draws from tokens.css;
   no new colors are invented here. States are attribute-driven
   ([aria-pressed], [data-state]) because the demo scripts must stay
   CSP-clean: no inline handlers, so no inline state styles either.

   2026-08-25: this file was calling two tokens that have never existed
   (--mono, --r-md) and their hardcoded fallbacks were doing all the work,
   which is exactly the failure shell3.css wrote down: a fallback only fires
   on a broken page, and then it paints the wrong value. Every var() below
   now names a real token from tokens.css and carries no second argument.
   Timing joined the house budget at the same pass: the pills transition on
   --t-hover and settle on --t-release, same as every control on the site. */
