/* rz-cx-handbook.css — the Cx field manual pages (cx-handbook/*.html, built by tools/build-cx-handbook.py)
 *
 * Loads after css/rz-hub.css and css/rz-tool.css and uses their tokens. Reading register: graphite, one
 * amber, IBM Plex Sans for prose, JetBrains Mono for numbers and labels, 1 px hairlines, radius <= 4 px,
 * no gradient, shadow, pill or icon. The SVG drawings are paper-white sheets with navy ink; they are
 * framed as sheets and never inverted, so they read the same in both themes.
