/*!
 * JBM Spread Map — styles ported verbatim from the Astro site
 * (src/styles/blocks.css + tokens.css). The map markup is namespaced under
 * .spread / .scroll-story, and the JS-appended dive overlay under .story-scene /
 * .spread-flyin / html.story-open, so collisions with a host theme are unlikely.
 *
 * Fonts (Fraunces, Inter, JetBrains Mono) are enqueued separately by the plugin
 * from Google Fonts. --nav-height is deliberately NOT set here: the map's rules
 * fall back to 0px (full-bleed) when it's undefined, and the JBM Theme defines
 * the real header offset when it's active — setting it here would override the
 * theme for every other block on the page.
