/**
 * Sticky TOC for Elementor — frontend styles.
 *
 * Notes:
 * - All rules are scoped to .stoc and its named children — no universal `.stoc *` selector.
 * - Baseline rules use :where() to keep specificity at 0, so theme/user styles trivially win.
 *   Elementor's per-instance selectors (which prefix with .elementor-element-xxx) still beat
 *   our baseline because they have higher specificity.
 * - Box-sizing is set ONLY on stoc-prefixed elements so it can't leak to nested user HTML.
