/* Keystone marketing — "presidential seal": red, white & blue.
   Type: Playfair Display (serif display) + Source Sans 3 (sans body).
   Light-mode only, symmetric, generous spacing, thin blue rules.
   --blue is the mid-tone accent (rules/borders/numerals on white or navy);
   text sitting directly on the near-black --navy background uses the
   existing light #cdd8ee instead of --blue, for contrast (see usages). */
