/*
 * Artifact styles for the workspace demo.
 *
 * Every rule reads only --ds-* custom properties, bound at runtime from a real
 * design system in `design-systems.json`. No brand-specific rule lives here:
 * switching the system is a token swap, not a stylesheet swap.
 *
 * Each layout is composed like the real thing it stands for - a poster fills
 * its sheet, an app screen carries a tab bar, a slide carries a data panel -
 * because a schematic wireframe would undersell what the product generates.
