/**
 * Case Study — scoped, light-only "document" surface.
 *
 * Ported from the case study's original embedded <style> and scoped under
 * `.case-study` so it styles only the case study article and never leaks into
 * the rest of the site. The surface keeps its own light palette regardless of
 * the site's dark mode (the SVG figures have light colors baked into their
 * markup), while the theme header/footer/nav around it still follow the active
 * theme. Loaded only on the Case Study template (see zm_assets()).
