   blog.css — HELMD blog (v1: Hims-clone styling)
   Pairs with legal.css (reset + .site-footer). Load legal.css FIRST,
   then this file.
   NOTE: Hims uses the licensed Adobe font "sofia-pro". As a free
   stand-in we use Poppins (geometric sans). Swap to a licensed
   Sofia Pro (or chosen brand face) in a later HELMD-ify pass.
