   Loaded ONLY by the `force` and `forces` templates, so site.css, and every other page, is unchanged by them.
   Built to her mockups (mockup_force_global.jpg, mockup_forces_index.jpg) from site.css's tokens: the five force
   colours (--ff-global …), Roboto, the soft shadows and card radii, navy #071329.
