/**
 * PEPTIDE.Power CRO — doc-layout (unified text-page layout).
 *
 * Branded SIGMA-style documentation layout: <h1> + summary header, a sticky left
 * table-of-contents, and a consistent reading column. Scoped entirely under `.pp-doc`
 * so nothing leaks to the rest of the theme. Tokens match the PeptidePower brand
 * (home-intro.php / faq-cta.php): purple #4b2fd6 / #5d4f89, pale panel #f7f5fb,
 * border #e6e4f3 / #d1c9e6, heading ink #15123a / #4a3f73.
 *
 * Enqueued only on in-scope pages (includes/doc-layout.php → ppcro_doc_layout_enqueue).
