   Every rule is scoped under .rdx-page and every class is rdx- prefixed, so
   nothing here can reach the shared layout, the header/footer, or any other
   tool page. Colours come from the site's own theme tokens (--surface, --text,
   --line, --primary…) rather than a private palette, so this page follows the
   light/dark toggle automatically instead of needing its own dark block.
