Spotlight Tour

SpotlightTour walks users through several UI targets in order. Add SpotlightTourStep children with optional anchor_id values matching stable DOM id attributes (omit to center in the viewport) and optional per-step anatomy slots; bind open to start the tour. The built-in footer provides Back, Next, and Finish. Wire on_finish to record completion in your app state. Prefer SpotlightPopover when the user opens help from a button; prefer this component when the app drives a multi-step walkthrough. Skip and dismiss are not first-class props yet.
