* Back button on feed views: drilling into a tag or source from a card now
remembers where you came from (a small history stack), and a "← Back" appears
in the view header to return there — chains of drill-ins included. Top-level
nav (rail/bottom bar) resets the history.
* Article page: the source name is now a link into that source's in-app feed
(/?source=<id>); the SPA reads the param on load and opens the source view
(label falls back to the loaded feed's source name). Completes the
"cards-only v1" — source is clickable on /a/ too now.
