   --------------------------------------------------------------------------
   Opening a project card on the home page grows the card into this
   full-screen sheet; inside are that project's screens from work.html,
   stacking like on the work page (css/work.css, js/work.js). It has its own
   link (?project=stokr). Built by js/project-sheet.js.

   2. Close button
   3. End of the sheet: next project, all work
   4. Shared link: page waits hidden until the sheet is up
