   includes/substrate.css
   VioLev fork of the SecureLynx Intelligence Archive theme.

   The archive lives on VioLev now (a large nod to SecureLynx, not borrowed
   chrome). VioLev's colors.css already carries --cyan verbatim plus matching
   --text-*, --bg-panel-strong, --transition-*, and --radius-*; only the four
   tokens below are missing, so they are the entire SecureLynx dependency. The
   panel shade it inherits is VioLev's faintly-violet one, so the archive picks
   up a subtle VioLev undertone beneath the SecureLynx cyan. Below the tokens:
   a self-contained hero (replaces SecureLynx services.css) and the lightbox
   service button, then the dossier wall + lightbox + loupe forked verbatim
   from SecureLynx dossiers.css.

   SecureLynx Intelligence Archive - the dossier wall + lightbox viewer.

   Sits on top of the corporate stack (colors/base/navigation/components +
   services.css as $cssMain). Cyan-first, classified-archive treatment to match
   the art. The card art is a light thumbnail; the full sheet loads only in the
   lightbox. Cards are real <a> links to the full image, so the gallery works
   with JavaScript off - the lightbox is pure enhancement.
