/* Trims the toolbar down to what makes sense for a single, read-only
   portfolio document: sidebar toggle, find, page nav, and zoom.
   Hidden via CSS rather than removed from the HTML, so PDF.js's own JS
   (which looks these elements up by id during init) never hits a null
   reference — they just take no space and can't be interacted with. */
