/* ===========================================================================
   HALSYS PRODUCT HUB - BRAND STYLESHEET
   ---------------------------------------------------------------------------
   Palette taken from the Halsys Brand Guidelines (V1, November 2021).
   The previous portal used #C8102E, which was never a guideline colour.

     Red       #d13139    Charcoal  #4a4a4a
     Grey      #bcbcbc    Paper     #f9f9f9
     Blush     #fde5da    Lime      #95c11e    Mist  #e2e8ea

   Two working reds, not one. Pure #d13139 on white measures 4.99:1 for
   contrast, which only just clears the accessibility floor and is tiring at
   small sizes. The brand red does the large areas; the deeper #b82a31 does
   links and small text, where it measures 6.15:1. They are hard to tell apart.
