/* About page — engineering dossier layout.
   Two columns: a sticky datasheet-style identity panel + a narrative column.
   All colour comes from the --rae-* token layer in rae-theme.css, which is
   already theme-scoped, so light mode follows automatically. Only translucent
   overlays and shadows need explicit per-theme handling. */
