  /*
   * Even though `MessageRun` is notionally a generic container for markup, we restrict the swatch
   * to precomosed test messages. Swatches are available to all users, including
   * technically-unsophisticated ones, and anything rendered in a swatch runs in the same origin
   * context and the same cookie context as the rest of the client.
   *
   * This makes it possible that a user would be persuaded to enter something into a swatch that
   * then runs _as them_, interacting with Pilcrow via its API or accessing client-stored data.
   *
   * As a proof of concept, `<img src="x" onerror="console.log('oh no')">` should not run the log
   * statement. With generic HTML entry, it would do so.
   *
   * Users who want to experiment with free HTML are encouraged to edit the swatch for themselves.
