   --------------------------------------------------------------------------
   COMPONENT API (class -> purpose -> expected markup)
   Theme: <html data-theme="light|dark"> overrides OS preference. `.js` class on
   <html> enables reveal animation (content visible without JS).

   LAYOUT
   .container            centred width wrapper (max 1180px, 16px gutters)
   .section              vertical-padded <section>; .section--soft = tinted bg
   .section-head         <div class="section-head"><p class="eyebrow">..</p><h2>..</h2><p class="lead">..</p></div>
   .eyebrow              small uppercase teal label above headings
   .lead                 larger muted intro paragraph
   .grid-2/.grid-3/.grid-4  responsive card grids (minmax(0,1fr)); 4->2->1, 3->2->1, 2->1
   .reveal               scroll-reveal; JS adds .is-visible

   BUTTONS / BITS
   .btn .btn-primary | .btn-ghost   <a class="btn btn-primary">; .btn-lg bigger; .btn-block full width
   .tag                  small pill label (e.g. "Illustrative"); .tag--accent
   .card                 bordered surface; .card--hover lifts on hover
   .card-icon            <span class="card-icon" aria-hidden>svg/emoji</span> in a card
   .check-list           <ul class="check-list"><li>..</li></ul> teal check bullets

   NAV
   <header class="site-header [nav-open]"><div class="container nav-inner">
     <a class="logo" href="#top"><svg class="logo-mark">..</svg><span>Operwise</span></a>
     <nav id="site-nav" class="site-nav" aria-label="Primary"><a href>..</a>... <a class="btn btn-primary nav-cta">..</a></nav>
     <button class="theme-toggle" aria-label>..</button>
     <button id="nav-toggle" class="nav-toggle" aria-expanded="false" aria-controls="site-nav"><span class="nav-toggle-bar"></span></button>
   </div></header>
   Under 1024px #site-nav hidden unless .site-header.nav-open.
   Theme toggle: show icons with <span class="icon-sun"> and <span class="icon-moon"> inside; CSS shows the right one.
