 * Storytime Theater · the scrolling stories  (assets/css/kids-story-scroll.css)
 * includes/views/kids-story.php · data & art: includes/kids-story-scroll.php · camera: assets/js/kids-story-scroll.js
 *
 * An always-dark page in both themes (it sets its own Temple Dark tokens: ivory #FCFBF7 and gold on deep night glass,
 * far above AA), like the Storytime Theater's stage band.
 *   - .kss-stage: sticky, one viewport tall (100svh), pulled up under the story by a negative margin, clipped
 *     (overflow: clip), so the 4:1 world (.kss-world, height 100%, width 400% of the height: about 500 phone widths)
 *     never widens the page. The world is moved only by transform (translate3d + scale from its top-left corner);
 *     will-change is set by the script only while the camera moves, so the art re-rasterises sharp when it settles.
 *     Without JavaScript a CSS transform frames Act 1's focus (x 1035 of 6000 = 69% of the stage height).
 *   - Ambient light (.kss-ov: the lamp, the three doorways, the presence under the banyan, the dawn, a lit window,
 *     fireflies) is HTML laid over the world at the same world coordinates (left / top in % of the world), so its gentle
 *     motion is composited and never repaints the big SVG. It moves only when the script marks the page .is-alive
 *     (motion welcome and "Keep the stage still" not pressed) and never under prefers-reduced-motion.
 *   - The traveller (.kss-hero) stands on a dark ridge in the foreground; it bobs (@keyframes kss-float) and leans with
 *     the camera's speed; under reduced motion it stands still.
 *   - The story (.kss-track) scrolls over the stage: one panel per card, at least one viewport tall, its card on dark
 *     glass (right-hand column from 900px, full width on phones), body text 18px+ for reading aloud.
 * Phones first: no horizontal scroll at 320px (.kss is overflow-x: clip), every control at least 44px, buttons
 * position: relative.
