/* Little Cloud Software — marketing site.
   Palette is built from the two brand colours. Navy carries text and structure;
   cyan is decorative only — it measures 2.2:1 on white and can never be trusted
   with type. Typography matches the printed proposal and rate sheet so the site
   and the documents read as one company. */
