/* ============================================================
   GEN CHEM INTERACTIVES: BOOK TOKENS
   The per-book tokens of docs/textbook/STYLE_STANDARD.md section 2.2, in both
   themes, plus chem's subject families. Reset, page foundation, type scale and
   fonts come from the shared runtime (public/textbook/base.css).

   --bad is a text and outline colour only, and no subject colour shares its
   value (standard, 2.2). The subject reds (nucleus, hot) are the accent
   vermilion, so --bad is a deeper red in the light theme and a paler one in
   the dark theme. Green means correct only. Zero em-dashes.
