title: Sphinx documentation: define but hide heading/title text
body: <p>I'm using Sphinx to document a Python package. The top of the title page / splash page holds a graphic with a logo and text for the project. This gives the visual appearance that I want, but because I have defined no top-level heading the page <code>title</code> metadata (which renders in the browser tab) is set to <code>&lt;no title&gt; — my project name</code>.</p>
  
  <p>Is there a way I can do one of the following?</p>
  
  <ol>
  <li>Define a title text but not have it render as a heading on the page?</li>
  <li>Set the <code>title</code> page metadata some other way?</li>
  </ol>
