/* Public JSON Reader tool (/json-reader).
 *
 * Built on theme-dark.css and auth.css (aurora backdrop, turning card edge,
 * gold button, ghost buttons, --auth-* tokens), like the other apps; this
 * file adds the hero, the tool card (toolbar, input and output panels, error
 * card, coloured code, tree) and the content sections.
 *
 * Layout, mobile first: heading and intro, then the tool card, then the
 * content. Inside the card the input and output panels are stacked, and sit
 * side by side from 1024px. Only the editors scroll sideways, never the page.
 *
 * Motion (transform and opacity only, nothing under prefers-reduced-motion):
 * floating braces and a pulsing node graph in the hero, a sliding bar while
 * working, and the scroll reveal of the content (start states only after
 * main.js marks <html> with `jr-reveal`). The heading and intro never animate.
