/* Embed mode — hide chrome when loaded inside an iframe (?embed=1).

   header/footer; we keep just the page's hero + main content.

   Page-agnostic rules apply to every page that uses base.njk or has the
   embed script inlined. Per-page chrome (quarry's "how-it-works" sections,
   etc.) is also hidden here. To hide a new element in embed mode without
   editing this file, add `data-embed-hide` to it in the source. */
