/* HRC Ledger — marketing site.

 * The palette and type below are NOT invented for the web: they are the app's own
 * design tokens, lifted from apps/mobile/src/theme/index.ts and theme/typography.ts.
 * Change them there first, then mirror here.
 *
 * The one rule worth restating: Instrument Serif appears on the money figure and
 * NOWHERE else. typography.ts calls it "the only serif, and a deliberate break
 * (it's the emotional center of the screen)". Same rule holds on the web.
