/* ---------------------------------------------------------------------------
   mockup.css - throwaway stylesheet for the /preview/m1 and /preview/m2 studies.
   Delete it with the mockup directories once a direction is chosen.

   THREE BLOCKS, kept apart on purpose so the shared-design report can count them:
     1. BASE      - adapted: the controller's base, with the font paths repointed
                    from /static/fonts/ to /assets/fonts/ (the website's copies).
     2. CONTROLLER- verbatim from felhom-controller style.css @ dcd89364a4.
     3. MOCKUP    - new: only what the studies need and the product has no answer for.
