A) Blog: add prominent playground-cta card at the end of each post.
Styled with brand gradient border, eyebrow + headline + CTA button.
Remove the buried related-cta line from related-posts.html.
B) App: load a meaningful XSLT welcome example for first-time visitors
(no localStorage) and auto-run it immediately (autoRunReady=true),
so new organic users see live output instead of a blank editor.
