/* ============================================================
   Phone layout — pbb.sh's mobile treatment, measured off the
   live site: the tall centered sidebar collapses into a 129px
   horizontal profile strip (72x88 avatar left, name/socials/
   location right), a divider, then the page content — all in
   ONE card with a 6.4px gutter. Content starts around y=250
   instead of y=700, and the strip now renders on every page
   (pbb keeps its identity block everywhere).

   Must stay last in this file: it re-enables .pb-side on
   subpages, which an earlier rule of equal specificity hides.
