Apply the publication's thesis to its own design

- Self-host Newsreader/Inter/IBM Plex Mono via fontsource (no external requests)
- Open each story with its trust anatomy: pattern moved into the article
  header, expanded by default; review date flags itself when overdue
- Homepage shows only what exists: podcast, book, and guide placeholders
  replaced by one honest roadmap note
- Story-card diagram now drawn from the story's own trust pattern; the
  failure link encodes status (dashed developing, broken disputed, solid
  resolved)
