/* Backstage design system.
   Light, precise, monochrome. One accent (international orange) marks what you act on: a Moment, the
   active step, a report from the room, the primary control. Everything else is ink and slate.
   Headings, labels, buttons, status and data are JetBrains Mono. Body copy and inputs are Inter.
   Square corners, 1px borders, no pills, no gradients. One file for landing, tour and console. */
