/* MedFirst Tech — campaign landing pages
   Brand tokens live here. Swap these values to rebrand the whole site.

   Palette is taken from the MedFirst logo: the blue of the ECG line, and the
   yellow of the heart. Hexes are sampled by eye from a PNG — replace with the
   exact brand values if a style guide exists.

   The yellow is decorative only. At roughly 1.5:1 against white it fails every
   contrast threshold, so it never carries text or sits behind white type. Use
   --accent for rules, marks and highlights; use --accent-ink where a warm tone
   has to be readable. */
