/* Praxis — the QQ signature chassis (Doctrine interface grammar, re-plugged for Praxis).
   Source of truth: the QQ Gold Standard design system.
   Same chassis at every size: topbar + views + bottom tab nav. No sidebars, no SaaS chrome.
   Provider-neutral: no provider/model names anywhere user-facing.
   Documented deviations from Doctrine: --text-3 lightened #6B7280 -> #7D8694 (WCAG AA 4.5:1
   for sub-16px mono labels); Deep depth state uses green (the reference badge-slot accent),
   keeping gold scarce next to SEND. */
