/* kreaudio.com
 *
 * One dark theme, on purpose: the brand is aurora light on near-black, and
 * so is the app. One accent, Aurora Cyan, taken from the brand image. The
 * type is the system's own (San Francisco on a Mac, Segoe UI on Windows),
 * the same faces the app uses, so nothing is downloaded.
 *
 * Shapes: containers 24px, pictures inside them 14px, controls fully round.
 * Layers: the aurora canvas is -1 (fixed, behind everything), the nav 20,
 * the skip link 30. Sections that should hide the aurora carry their own
 * background; the hero, the stage and the closing call stay clear.
