/**
 * DLP shared docs layout (D-166) — single source of truth for the
 * fixed-sidebar documentation chrome used by framework, faq, dlp-week1..4.
 *
 * Replaces six near-identical inline copies. The geometry guarantee: at
 * desktop widths the sidebar column is reserved by BODY padding, so every
 * body-level element (main content, site footer, standing-disclaimers aside,
 * hq-widget) clears the fixed sidebar by construction — the D-165 headline
 * break was content OUTSIDE .main-content sliding under the sidebar, because
 * the old layout only protected .main-content via margin-left.
 *
 * Pages opt in with body.docs-layout (set body_class in the page template)
 * and may override --docs-accent (sidebar-toggle color) and
 * .main-content max-width in their inline styles.
