/* Brett Reynolds - homepage v3
   STANDALONE. Deliberately does not layer over style.css: the v2 homepage
   broke because an override sheet collided with the base sheet on specificity.
   This file owns everything the v3 homepage needs.

   Type scale, four sizes only:  0.875 / 1 / 1.25 / 1.75 rem
   Colour roles, five:           bg / text / meta / rule / link
   Measure is in rem, not em, so every prose block shares one right edge.
