/* ==========================================================================
   Brand colour system, built only from George's palette:
   navy #16325C · blue #1793CE · dark blue #0B6A99 · slate text #334155 / #475569 / #64748B
   border #DCE8F2 · soft #F4F9FD · white · green #18A058 · red #E5484D.

   The base colours stay as they are. This layer adds what a palette needs to work
   as a system: tonal steps of the navy and the blue, navy-tinted shadows, a rhythm
   of white and soft sections, and clear roles:
     navy      → headings, primary buttons, dark surfaces (CTA band, footer)
     dark blue → links and interactive states (5.9:1 on white)
     blue      → highlights only: dots, rings, glows, icons, large text
   Loaded after main.css and wp.css; delete the enqueue to go back.
