/* FittedCV marketing site — page-specific layer on top of the shared design system
   (../fittedcv-brand.css: tokens, font, reset, buttons, eyebrow). Load fittedcv-brand.css
   before this file.

   High-contrast alternating sections carry the "modern tool" feel instead of gradients or drop
   shadows: .section-invert always renders as the *opposite* tone from the page background via
   the shared --invert-* tokens, so the same alternating rhythm holds in both light and dark
   mode — light mode gets white-page/black-band, dark mode gets black-page/white-band. */
