   CASE-STUDY PAGE TEMPLATE
   Loaded after tokens.css + style.css, so nav, buttons, chips, quote and stack chips are the same
   components as on the home page. Only what is specific to a case-study page lives here.
   To make a new case study: copy gymdesk/index.html to <project>/index.html and edit the content.
