/* fold.geneticker.com — overlay on the shared Geneticker theme (styles.css,
   imported verbatim from Cipher). This sheet (1) sets Fold's own accent so it
   reads as a sibling of Cipher (teal) / Decipher (indigo) / Swap (violet) /
   Locus (cyan) / Logo (mark-teal) — Fold is AMBER — and (2) adds the components
   unique to a protein-structure browser: the viewer stage, the sequence and
   topology strips, the classification grids and the variant tables.

   DARK-MODE RULE (see darkmode-token-traps): every token and every hard-coded
   accent-rgba rule is declared THREE times — light :root, explicit
   [data-theme="dark"], and the @media prefers-dark block, with the two dark
   blocks byte-identical. Add to all three or one theme path silently misses it.
   Never write a colour whose only definition lives inside a media query. */
