/* ---------------------------------------------------------------
   AI Safety and Security Field Map: component styles.

   Ported from docs/design/reference/src/head.html into packages/fieldmap
   (docs/plan/mvp.md task 1). The reference page defines its own colour
   tokens (--page, --ink, --sea, ...) at :root. The site instead loads
   docs/design/tokens.css globally (the --fm-* names, see
   docs/design/02-tokens.md), so this file only aliases the reference
   script's variable names to the --fm-* tokens rather than keeping a
   second set of values: the script (and a couple of inline `style=`
   attributes it writes into the SVG it draws) still reads --page, --ink,
   --frame and so on, unchanged, so aliasing here means the script's
   internals don't have to be touched to pick up the design tokens.

   The standalone build (docs/design/reference/src/build.py) is separate
   from this file and unaffected by this port: it embeds a data file into
   docs/design/reference/src/head.html and body.html as they stand, with
   their own unaliased --page, --ink, --sea, ... tokens. It doesn't read
   this file.
