/* =========================================================================
   Sower Gateway — design system (student site + admin portal)
   2026-11-10 "mature" refresh. Stands on its own: no longer builds on sower.css,
   whose rounded, child-friendly Academy look doesn't suit adult candidates.

   Idea: a well-set examination paper. Quiet bottle-green and ink on cool paper,
   a brass keyline used sparingly, a sober grotesque for the interface and a
   book serif for anything a candidate has to READ (notes, passages, questions).
