   whole site should use. Do not paste a second,
   separate <style> lightbox block into any page

   iPad scroll + clipped-content bug. Every gallery
   page should link this file and reuse the same
   #lightbox / .lightbox markup.

   Pages whose JS sets scrollY and toggles this class (e.g. comets.html)
   get a smoother iOS scroll-lock; pages that don't reference it are
