<!--
  Vue port of packages/react/src/components/ui/PrintPreview.tsx —
  PrintStyles injection + a small print-trigger helper. Heavy lifting
  (parsePageRange, openPrintWindow, triggerPrint) lives in core; this
  SFC just renders the inline `<style>` block that suppresses chrome
  during browser print.
