/* Beanbook website
 *
 * Paper, ink, and one teal rule -- the palette of the app (app/ui/theme/Colour.kt), turned
 * up for a page whose job is to be remembered. A ledger is ink on ruled paper, so the page
 * is a ruled sheet with a double margin rule; headings are underlined the way an accountant
 * underlines a total; terracotta marks only what is not finished yet.
 *
 * Type: Archivo (OFL, variable weight and width) for display, Roboto for prose, Roboto Mono
 * for figures and Beancount source. All self-hosted; the site makes no third-party request.
