/* Shared shell for the site's secondary pages (About, Sources, Privacy,
   Share, Follow, Certification) — tokens, nav and footer copied verbatim
   from index.html so these read as the same product, not a separate
   skin. index.html keeps its own inline styles (a deliberate, documented
   trade-off — see its <style> comment) and is not changed to use this
   file, so nothing here can regress the homepage. */
