/* Shared foundation for every page on assetdiary.in: design tokens, the light
   and dark themes, the base element styles, and the header/footer chrome that
   appears on all three pages.

   Page-specific rules stay in a <style> block in the page itself — the hero and
   feature cards belong to the landing page, the .steps list belongs to
   delete-account. Only things used by more than one page live here.

   Two knobs pages set to tune the shared rules, since the marketing page and
   the document pages differ on both:
     --wrap       content column width (landing is wide, documents are narrow)
     --body-line  body line-height (documents read better looser) */
