/* story.css — the scroll-narrative skin the product front doors share.
 *
 * FBMCPF-510. Started life inline on /nativecad/ (FBMCPF-509); /featureboard/
 * and the /products/ shelf wanted the same feel, so the skin moved here and the
 * three pages read as one site. What it gives a page:
 *
 *   .progress            2px scroll-progress bar, fixed at the top
 *   .site-nav            sticky one-line nav (scrolls sideways on phones, wraps
 *                        on desktop), with an optional .theme-toggle inside it
 *   .hero / .hero-grid   full-height hero on desktop, top-aligned on phones;
 *                        h1 lines rise in, .lede and .cta fade in after
 *   .hero-art            an inline SVG that draws itself (stroke-dashoffset on
 *                        pathLength="1" elements) then hovers; .tag pills
 *   .stats / .stat       counters — [data-count] numbers count up on arrival
 *   .chapter             sticky label rail (.ch-head) + card grid (.ch-body)
 *   .card / .rv          cards that arrive on their own IntersectionObserver
 *   .steps / .step       a NUMBERED sequence — use only where order is real
 *   .tools-section       wrapper for the tool-reference component
 *
 * Tokens: the page sets --accent (default NativeCAD blue). Light palette on
 * :root, dark under html[data-theme="dark"]; a dark-only page just stamps the
 * attribute. --story-top is the height of anything fixed above the page (the
 * nav.js bar is 80px) so sticky offsets clear it. story.js drives the motion;
 * without it, and under prefers-reduced-motion, everything is simply visible.
