Authoring Bento decks

A Bento deck is one self-contained .bento.html file. The document is plain JSON in a single block:

<script type="application/bento+json" id="bento-doc"> { "format":"bento/slides", ... } </script>

You edit that block only, in place. Escape every < in the JSON as \u003c so it can never contain a literal </script>. Leave the rest of the file (the compressed runtime) untouched. In a chat context instead, the user copies the JSON out (Save ▾ → Copy document JSON) and pastes your replacement back (Save ▾ → Replace from JSON…); window.bento.loadDoc(json) does it from the console.
