/**
 * `highlight_node` + `hide_highlight` (batch-13 Should) — visual feedback loop
 * for AI agents picking DOM elements.
 *
 * Probe-confirmed (2026-05-17):
 *   - DOM.highlightNode ✅ (needs valid nodeId)
 *   - DOM.hideHighlight ✅
 *
 * The Apple WIP `DOM.highlightNode` schema differs from CDP — uses
 * `highlightConfig: { contentColor: { r, g, b, a } }` etc. Default config draws
 * a translucent blue overlay that's visible on screen + in screenshots.
