 * Sapwood Grove — page styles (v1.0.0)
 *
 * Loads ALONGSIDE polaris-home.css (which provides the shared header chrome:
 * .pp-header, .pp-panel, .pp-topbar, logo, search, footer, and the header
 * scroll/compact behavior). This file adds only the Sapwood body: the
 * three-column grid, the Table of Contents, the action buttons, the fixed
 * scroll-logo, and the back-to-top arrow, plus the mobile stack.
 *
 * Design tokens (--navy, --forest, etc.) are defined in polaris-home.css :root.
