   IELTS Speaking Mock — design tokens
   A calm exam room: deep teal ink on warm paper. Amber is reserved
   for the LIVE recording state and timers; teal-green marks the
   examiner (authoritative); indigo marks the candidate's own voice
   (self-assessment), so the two reads never blur in the comparison.
