Spotlight Tip

SpotlightTip shows a coaching panel anchored to the element whose id matches anchor_id. Bind open to control visibility from your app — no trigger slot. Assign stable DOM id values before anchoring — tips match on anchor_id, not component refs. Set backdrop to SpotlightBackdrop::Spotlight to dim the page and cut out the target; use SpotlightPopover when the user opens help from a button instead. Show one programmatic tip at a time; re-anchor when scroll or resize moves targets.
