/* =============================================================================
 * Performance division homepage (front-page.php) — scoped styles.
 *
 * Every selector lives under .perf-home (plus the nav-adjacent bits the
 * template renders itself). The page is self-orchestrated multi-ground:
 * moss hero → paper body → moss process → paper CTA — so it PINS its light
 * tokens locally and ignores the sitewide theme toggle (which the template
 * also hides from its nav). Dark sections re-scope via .ph-dark, exactly
 * like hive-mind's .hm-section-dark convention.
 *
 * Colour law (style.css header): Volt is never text on light grounds —
 * text-level accents on paper are Pine via --accent-fg; Volt appears on
 * light only as fills/chips/underlines. Ember appears exactly once (the
 * P&L card live dot). Borrowed division colours appear exactly once (the
 * divisions strip dots).
 * ============================================================================= */
