/* fintechaustin.com — OWN DESIGN (2026-11-14): "the green-bar ledger".
   Building a fintech in Texas is licensing, money transmission and audits: the world of the
   printed ledger. So: fanfold green-bar computer paper (alternating pale green bands) with
   tractor-feed margins, JetBrains Mono for headings and labels, guides as numbered ledger
   accounts, banker's green as the one accent. Body stays a readable system sans.
   Fonts self-hosted (static/fonts, SIL OFL). Styled ENTIRELY by this file ("own_css"). */
