   Follows the visitor's OS setting.

   Palette per the SAFi branding standard: green is the only accent, and the
   surfaces run down the NEUTRAL black-to-white axis. This block previously used
   a warm cream text (#F8F6F1) on cool blue-slate surfaces (#1E2432 / #161B26),
   two off-palette families in one widget, justified as matching the marketing
   site's dark theme. That claim did not hold up: the site theme's own palette is
   navy and orange, so the values matched nothing and only made the widget read
   as a different product from the app it represents.

   Mostly a token swap — the widget was already built on custom properties. The
   rules after the :root block are the handful of places that hardcode a light
   value and therefore cannot be reached by swapping tokens.

   The brand greens are deliberately unchanged: #16a34a on #171717 clears 4.5:1,
   and the header gradient reads well on dark, so the widget keeps its identity.
