   Used by:  pages/atelier.html, pages/spectacles.html,
             pages/galerie.html (+ js/gallery.js)
   Meant to be reused by pages/lecture-bilingue.html

   Load it AFTER css/style.css - it relies on style.css for
   the design variables (--cream, --line, --terra, --serif) and
   for .container, .underline, .link, .btn and .support-box.
