/*
 * theme.css — BillDesk's design-system values.
 *
 * A ledger, not a toy: a deep teal accent (money that is settled), quiet
 * green-grey neutrals, Inter for the work and Bricolage Grotesque for the
 * headings, JetBrains Mono only for figures that line up. Light opens; dark
 * is its own palette with a brighter teal, not the light one inverted.
 *
 * --x-paper* is the printed invoice: a document stays white in both modes,
 * so it reads the same on screen as it does on paper.

 * figures count up (app.js). Everything RESTS visible; the animations only
