/* =====================================================================
   STF Research (Labsboard) — embedded styles
   The Labsboard runs INSIDE the platform's own shell (sidebar + topbar +
   identity switcher + theme). Its component CSS is scoped to .labs-root via
   @scope so the platform's generic class names never collide, and every
   Labs token is bridged onto the platform's design tokens here, so light /
   dark mode and the amber Research accent flow through automatically.
   The Labsboard's own .shell / .sidebar / .topbar / .login rules are kept
   but inert — that markup is never rendered (the platform owns the frame).
