* 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. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
