test_embed_chat.py

"""DETERMINISTIC EVAL -- the chat column alone, for waku.one to frame (spec 008).

The container's half of the embedded chat:

  A. GET /embed/chat serves the dashboard's chat column and nothing else of
     the dashboard, with the allowlist the gateway sent it (or the default).
  B. The `report` event draws a card with "Open report", and a
     `consolidation` event's `kept` lists the facts, in the dashboard's chat
     too -- rendered here from recorded events, in node.
  F. The page posts to window.parent only with the framing page's origin as
     the target, only when that origin is on its allowlist, and never "*".

The gateway's half (codes, cookie, framing headers, the 403s) is in
evals/deterministic/hosted/test_embed.py. CI has no browser; the JavaScript
runs in node against a stub DOM, and skips where node is absent, like
test_static_js_parses.py.
