Tour support PurePanel

Editor assessment

The subject states the feature — the Tour component supports a PurePanel variant — naming the component and the added render mode, which is understandable within the component's established PurePanel convention. The body is a squash-merge bullet list (`feat: PurePanel` restated, snapshot updates, `test: coverage`) that shows the supporting work without explaining the use case (static, non-interactive display). Type `feat` is accurate; absent scope is tolerable since the component is named. Footers are absent. Style is clean — no trailing period, no junk. Clear and publishable, with the unstated motivation as the only notable gap.
