   Always use root-relative URLs (/academy, /img/...): 404.html is served at any depth.

   <body class="page-NAME">   (page-home, page-academy, page-founders, page-work, page-enquire, page-404)

   HEADER (identical on every page; put aria-current="page" on the current link):

     <a class="skip-link" href="#main">Skip to content</a>
     <header class="site-header">
       <div class="site-header__bar">
         <a class="wordmark site-header__brand" href="/" aria-label="ARTVERSE, home">ART<span>VERSE</span></a>
         <button class="nav-toggle" type="button" aria-expanded="false" aria-controls="site-nav">
           <span class="nav-toggle__label">Menu</span> <span class="nav-toggle__icon" aria-hidden="true"></span>
         </button>
         <nav class="site-nav" id="site-nav" aria-label="Main">
           <ul class="site-nav__list">
             <li><a class="site-nav__link" href="/academy">Academy</a></li>
             <li><a class="site-nav__link" href="/founders">Founders</a></li>
             <li><a class="site-nav__link" href="/work">Work</a></li>

         </nav>
       </div>
     </header>
     <main id="main"> ...sections... </main>

     The header is sticky. On a page whose first section is a full-bleed hero that
     should run UNDER the header (like the home page), add class "has-overlay-header"
     to <body>; the header is then transparent until the page scrolls.

   FOOTER (identical on every page):

   CLASS VOCABULARY
   ----------------
   Grounds      .theme-light (default) .theme-white .theme-mist .theme-dark  + .grain (film grain overlay;
                content inside a .grain block sits above it with position:relative; z-index:2)
                Each theme sets --bg --fg --fg-muted --rule --rule-strong --focus --accent-text.
   Layout       .wrap (max 1360 + gutters)  .wrap--narrow (880)  .section (vertical padding)  .section--tight
                .grid (12 cols) + .span-2 … .span-12 (collapse to 6 under 900px, 12 under 560px;
                keep with .span-sm-6)  .stack (vertical rhythm, --stack-gap)  .cluster (wrapping row)
   Type         .display-xl .display-l .heading .quote .hero-thin (giant thin Jost)  .caps
                .eyebrow .lede .body-s .tag .caption .cn .cn-heading .num (Bodoni numeral, ink)
                .hero-title (the one hero h1 treatment: Bodoni caps block, used on every page)
                <em> inside display/heading = Bodoni italic in the ground's ink. One italic tail per page.
                .accent = Ember on dark grounds, ink on light grounds (contrast).  .muted
   Brand        .wordmark  →  ART<span>VERSE</span>   (one word; VERSE Ember; ART follows --fg)
                .lockup    →  <span class="lockup"><span class="wordmark">ART<span>VERSE</span></span>
                              <span class="lockup__div">Academy</span></span>   (primary horizontal)
                .lockup--stacked (division word centred below a short rule)
   Devices      .hairline-heading (Chinese .cn-heading + .eyebrow over a 1px rule)
                .tag-pair > .tag-pair__cn + .tag-pair__en  (one <b> keyword: ink + Ember tick on light,
                Ember word on dark)
                .ring (thin circle round a year/number)  .rule (1px line)  .vertical-word
                .corner-mark (inline SVG expand mark)  .index (step number + hairline dash; only where
                the order is real: the Method, the ten modules, the form steps)
                Use two or three devices per layout, never all.
   Sections     .section-head > .section-head__index (.eyebrow) + .section-head__main (h2 + .lede)
                .section-head--center: a centred statement (vary at least one head per page)
   Actions      .btn (outlined pill)  .btn--fill  .btn--sm   .link-arrow (tracked text link + arrow)
   Media        .frame (+ .ratio-1x1 .ratio-2x3 .ratio-3x4 .ratio-4x5 .ratio-9x16 .ratio-16x9 .ratio-3x2)
                .frame--settle (image eases in scale as it scrolls into view)
                .frame-offset (wrapper that draws an offset hairline frame)  .figure + figcaption.caption
                Silent loops: <video muted playsinline loop preload="none" poster="…" data-autoplay>
                (site.js plays them in view and pauses them off screen; reduced motion → poster + controls)
   Patterns     .page-hero (inner-page hero: giant thin word on mist + h1 + lede + media)
                .steps / .step (the Method, 01–05)   .credentials (bilingual credential list)
                .cta-band (closing enquiry band)     .field / .field__label / .field__input / .field__error
                .form-status  .visually-hidden / .sr-only  .hp (honeypot, off-screen)
   Motion       .reveal  (gentle settle as it scrolls in; content is ALWAYS visible at rest)
                Never put .reveal on an element that already uses transform for layout.

   MARKUP NOTES
   Put a real space between adjacent inline spans that read as separate words
   (".index" + ".eyebrow", lockup mark + division, name + Chinese name) so screen
   readers do not run them together; flex/grid layouts ignore that whitespace.
   Chinese text always carries lang="zh-Hans" (it switches to Noto Serif SC automatically).
   Images: width/height attributes always; loading="lazy" decoding="async" below the fold.
   Alt text describes the picture; only Nico and Goey are ever named.

   COLOUR RULES (contrast-checked)
   EMBER BUDGET: VERSE (wordmark and lockups), the active-nav underline, small ticks and
   state marks (focus, checked, error), and ONE feature element per page: the Method
   numerals on / and /academy (plus the PAGEANT spine), the RUNWAY spine on /work, the
   2026 hairline on /founders. Never a second colour: no Ember headings, rings or numerals
   elsewhere. Ember text only on Runway Black (5.99:1). Concrete text only on dark grounds
   and only at 15px or larger; smaller text on dark uses Studio Mist. Body text on light
   grounds is Runway Black or Graphite.
