/*
 * ClearFund narrated deck: look and layout.
 *
 * Colours, faces, radii and motion come from design/00-foundation/design-system.md
 * Appendix A (mirrored in apps/web/src/app/globals.css). Tokens are scoped to the
 * player and the standalone page so the deck can sit inside a host page without
 * redefining that page's :root.
 *
 * Sizing: slides are sized in em off one base font size. At stage widths above
 * 600px the base is 1/64 of the stage width (20px at 1280), so a slide is a fixed
 * 16:9 composition that scales as one picture. At 600px and below the slide
 * reflows into a stacked, readable phone layout with real pixel sizes.
