 * THE STORIES (js/stories.js): four scenes after the pull. Each
 * is a small Mac with one app open and the Kamui glass over it,
 * the real client writing inside. Values from MetalUI's tokens;
 * the depicted Mac keeps its own (mac/*.css).
 *
 *   .story          heading, stage, caption
 *   .story-stage    the Mac, scaled as one; the glass in real px
 *   .story-glass    the live window (the hero's .kwin, smaller)
 *   .story-cap      the hand-over line, shown when the scene ends
