/* ============================================================
   constans.dev — white-paper layout
   Long-form, formal, with Tufte-style sidenotes & marginnotes.
   Adapted to monospace + terracotta. Scoped under .wp so it can
   live alongside .post / .paper without conflict.

   Authoring contract:
     <article class="wp">
       <header class="wp-head"> … </header>
       <blockquote class="epigraph"> … </blockquote>      (optional)
       <div class="wp-body">
         <p class="lede">First paragraph (gets drop cap).</p>
         <p>Body text with a sidenote ref<span class="sn-ref"></span><span class="sidenote">The note itself.</span> continues here.</p>
         <p>Unnumbered aside <span class="marginnote">Aside.</span> floats into the margin.</p>
         <h2>Section heading auto-numbers as § 01</h2>
         …
       </div>
       <section class="wp-footnotes"> … </section>        (optional)
       <footer class="wp-foot"> … </footer>
     </article>

   Numbering: <span class="sn-ref"></span> increments a counter and
   prints itself as a superscript. The next <span class="sidenote">
   reads the same counter — so refs and notes auto-match as long as
   the source order is (ref, note, ref, note, …).

   IMPORTANT: sidenotes / marginnotes MUST be <span>, not <aside>.
   <aside> is flow content and the HTML parser auto-closes the parent
   <p> when it appears inside. <span> is phrasing content and floats
   correctly while preserving paragraph integrity.
