/* ============================================================
   Ledgerline — single-page site
   Hand-written CSS. No framework, no build step.

   Design direction: an accountant's columnar pad, updated.
   Pale sage paper with faint ruled lines, ledger ink, bottle
   green as the house colour, a highlighter for anything that
   has been reconciled, and red ink for the things that still
   need a human. Type is a quirky grotesque (Bricolage) over a
   neutral text face (Instrument Sans) with a monospace for
   anything that came off a bank statement.
