/* ============================================================
   HBV SEROLOGY INTERPRETER — component stylesheet.

   EVERY rule is prefixed with the root class `.hbs-si`, and the design
   tokens live on `.hbs-si` (not :root), so:
     · nothing here leaks onto a page, and no page rule reaches in;
     · the widget does NOT depend on .gin-topic-content or
       .rar-topic-content — it renders identically wherever it is mounted.
   No kit title class (.mk-group__title / .mk-factor__name / .mk-subhead …)
   is named anywhere in this file: the Micro-Kit owns the page type scale,
   this file only sizes the widget's own controls and readout.

   Reader text is #111111 throughout. No browser storage anywhere.
