/* =====================================================================
   The Missing Capability — site theme
   ---------------------------------------------------------------------
   One shared design system for every public page.

   Older stylesheets (brand.css, styles.css, lab/lab.css) are imported
   into the "legacy" cascade layer by each page. Everything here is
   unlayered, so it always wins over legacy rules without specificity
   battles. Legacy still supplies layout for components this file does
   not restyle.

   The idea: orange is "the missing piece" — the same orange that sits
   inside the C of the TMC logo. It is used for one meaning only:
   reasoning, the capability that is missing. Navy carries everything
   else.
