   R04 — THE READABLE EDITORIAL PAGE (locked from Patterns, 2026-07-10)
   How every long-form content page is built. (The homepage is its
   own animal — a landing page — and stays as approved.)

   1 · THE SKIM LAYER. A pure scroll must tell the whole story via:
       big serif chapter title → one-line italic cinnabar essence →
       one short opening paragraph → a hairline list → a "why" card →
       an italic serif close. Everything else folds.
   2 · THE DEEPER FOLD. Dense explainers live in <details class="deeper">
       behind one gold-underlined serif toggle ("The deeper story — …").
       NEVER explain why the page is layered this way in the copy.
   3 · BOLD FOR TIRED EYES. Every list item leads with its bolded key
       phrase; every paragraph carries at most ONE bolded core clause;
       "why" cards and closes bold the single sentence that matters.
       The boldface alone must read as a coherent summary.
   4 · ORNAMENT EARNS ITS PLACE. Per chapter: section-mark, watermark
       glyph @8%, one specimen plate w/ photo + post-stamp + label,
       drop cap on the opening, classical pull-quote, alternating
       ivory/cream bands, dark interlude between major movements.
