   Self-contained: vendors the "Aurora" design tokens + minimal base it
   needs (so it does not depend on any other stylesheet), then the tool
   styles. Scoped under .pa-page so it cannot leak onto the rest of the
   site (base.html nav/footer keep their own styles).

   Mirrors the output of Azure Pronunciation Assessment / Speechace:
   overall + sub scores, CEFR/IELTS estimate, fluency metrics,
   word-by-word accuracy, phoneme drill-down, recognized transcript.
