giles a8c095b1b3 host: article declares :body composition + decompose real posts (figure/iframe→cards) ...

Prep for importing a real blog post into the :body composition:
- article now DECLARES {:name "body" :type "Composition"} (layer 2 — the type defines that an
  article's body is a composition). The edit FORM + submit read scalar-fields only, so the
  Composition field never gets a stray text input (or gets nil'd on save).
- decompose handles real-post block kinds: <figure> → card-image WITH its <figcaption> as the
  caption (host/blog--find-child digs out the inner <img>); <iframe>/<embed>/<video> →
  card-embed with src as :url. card-embed's template now renders an actual <iframe> (videos
  play) instead of the url as text.

blog 175/175, full host conformance 404/404 (+ test: figure→card-image(caption) & iframe→
card-embed via import). Next: wipe content (reseed types+demos), import nt-live-encore.
