/* ==========================================================================
   Compound Embers — stylesheet
   Everything on this site is styled from this one file.
   Change it here, it changes everywhere.

   The idea: this is an accounting statement, not a blog.
   - Paper is faded green-bar ledger stock, not white.
   - Prose is serif. Every figure, label, and total is mono. (Real statements
     split exactly this way.)
   - Color means what it means in accounting: green = credit, red = debit/risk.
   - The signature: the double rule. It's the mark an accountant puts under a
     final total, and here it underlines every section heading.
