   GSA — Components: buttons, cards, accordions, marquee, sliders, forms
   Button behaviour mirrors the shortlisted theme (square edge, wipe-fill hover).
   Colour values come from the GSA palette; solid greens carry small text so
   contrast stays at AA, gradients are reserved for graphic accents.
