/* =============================================================================
   RAS Solutions - style.css
   Mobile first. Navy / royal blue with cyan accents.

   Colour rules baked into this file:
     - cyan is for accents, icons, underlines and focus rings only. Cyan is
       never used for body text. Where a blue text link is needed, the darker
       --link (#0284C7) is used instead, which passes contrast on white.
     - red is only ever used for a low stock count. Nothing else is red.
     - the hero gradient is the only gradient on the site.
