   senior.css  (loaded after style.css on every page)

   The senior-brand-designer layer (rebuilt 2026-10-03):
   - the homepage (.sr-*), and
   - the project-facts block on case studies (.cs-facts).

   Same system as the CV: Manrope, near-monochrome, one deep green accent
   (#2F5D46, the colour on the CV's name). The work carries the colour;
   the frame stays quiet.
