/**
 * Ravenore — reusable “i” help popover (hover, focus-within, click toggle).
 * Pair with static/js/rn-info-tip.js for click + outside close + Escape.
 *
 * UI Phase 7: calmer icon + popover (token borders, single shadow tier); keyboard
 * focus-visible on trigger; no loud gold ring on mouse focus.
