   InvoiceBolt — styles.css
   Concept: a precision financial instrument (cool porcelain control surface)
   beside a warm floating paper document. Money & metadata are set in a
   monospaced tabular face; prose in a clean humanist sans. Signature devices:
   the amber bolt mark and a perforated tear-line divider on the invoice.
