/* THE design tokens for the Liquid Biopsy Index. ONE definition.

   build_site.py reads this at build time and injects it into every CSS payload it emits, so a
   colour or a spacing step is changed HERE and nowhere else.

   ⚠️ WHY THIS EXISTS. There were FIVE separate :root blocks: two in build_site.py, one shared by
   the dossier templates, and one in each standalone dashboard. Of 42 tokens only two disagreed
   (--card written #fff vs #ffffff, the same colour; --shadow at .04 vs .05 alpha on a hairline).
   They agreed by hand-maintenance, not by construction. That is luck, and it is the friction that
   makes a redesign expensive: changing the accent meant finding five blocks and hoping.

   ⚠️ Do NOT define :root anywhere else. check_tokens.py fails the build if you do.

   ⚠️ The four files in dashboard/ are standalone published artifacts and cannot LINK a stylesheet,
   so their builders INJECT this instead. One source, two delivery mechanisms.

   ⚠️ --s1..--s8 are the CHART SERIES and are semantic: readers assume a colour means the same
   thing across pages. Do not reuse a series colour as UI chrome. --accent is #2a78d6 and --s1 is
   deliberately the same value; that is the one intentional overlap. */
