the documentation section doesn't seem to specify what exact types of expressions are being sent with each relevant message/event, and I'm wondering whether any of you had any experience with customizing HTML templates and have some information to share.

the <body> section of the current error.html template (generic 4xx/5xx error page) looks like this:

<body>
  <h1>{{title}}</h1>
  {{#if message}}
    <p id="message">{{message}}</p>
  {{/if}}
  {{#if detail}}
    <p id="detail">{{detail}}</p>
  {{/if}}
  {{#if detailHTML}}
    <p id="detail">{{{detailHTML}}}</p>
  {{/if}}
  {{#if console}}
    <p id="console"><code>{{console}}</code></p>
  {{/if}}
</body>
</html>

is there a resource detailing what exact expressions (messages) are being sent in any of the error "events"? for example, when should I expect to have just a message and title, and when should I expect detailHTML or console as well.
