/* ==========================================================================
   MyCareFriend design system
   --------------------------------------------------------------------------
   The register is institutional publishing, not premium SaaS. The people this
   site has to convince are a hospital executive and a federal program officer.
   Between them they spend their working lives in board packets, CMS Care
   Compare, the Federal Register and USWDS-built properties. What reads as
   credible there is a warm paper ground, one deep blue doing all the work,
   hairline rules instead of drop shadows, and numbers that carry a
   denominator. What reads as a startup is a blue-white ground with a
   saturated blue accent, which is the signature of every B2B site built since
   2019.

   Three rules hold the whole thing together:

     1. Ink on paper. Elevation comes from material and rules, not blur.
     2. Nothing below --ink-450 may hold text. That single line retires the
        entire low-contrast failure class the old stylesheet had.
     3. Colour never carries meaning alone. Every status also has a word.

   The brand blue is not being discarded. #1a6fc4 has been deepened one step
   and desaturated to #0E4C7A. Anyone who knows the old mark reads the new one
   as the same brand, older.
