/* Healthcare blue — the standard blue of UK health and care services (#005eb8).
   Brand and background only; RAG (--ok/--danger) left alone, as in the other
   themes, so status colours keep meaning the same thing everywhere.
   #005eb8 on white measures 6.4:1, so it passes WCAG AA for normal text both as
   a foreground and behind white text. */

/* The sign-in brand panel, which defaults to the original dark terracotta.
   Lightest at the top-left, deepest at the bottom-right. All three tones carry
   white text at 4.9:1 or better, so the heading and footer stay readable across
   the whole gradient rather than only in its darker half. */

   the panel in that very blue, so accent-on-accent would make them disappear.

   lightest panel tone (#0072ce) and more against the rest, clearing the WCAG
   large-text threshold at the size the headline is set in. */
