/* Brick & Bill — what things around a house actually cost.
   The idea: a sturdy hardware-store sign over a marked-up utility bill.
   - One memorable thing: the brick-red masthead with a brick-bond course
     under it (the name, made literal). Everything else stays quiet.
   - Headlines in Archivo at its widest cut: square, built, signage-like.
   - Body in Charter (system serif), blueprint blue-black ink on cool white.
   - Bold figures in the text get a meter-yellow highlighter, the way you'd
     mark the number that matters on a bill.
