/* ==========================================================================
   SYLLABUS TRACKER — dedicated page

   The old tracker was one inline-styled list: a big teal percentage and a row
   per chapter reading "0/2 Done". It only ever counted practice parts, so a
   student who tested a chapter instead of practising it saw 0%.

   This is the replacement. Same design-system tokens as the rest of the
   premium surfaces (test-history.css is its sibling), so both themes work with
   no second stylesheet. Prefix is syl- throughout.
