   * Rules of Static & Dynamic HTML:

   *    1.) We must generate static HTML unless the caller explicitly opts
   *        in to dynamic HTML support.
   *
   *    2.) If dynamic HTML support is requested, we must honor that request
   *        or throw an error. It is the sole responsibility of the caller to
   *        ensure they aren't e.g. requesting dynamic HTML for an AMP page.
   *
   *    3.) If the request is in draft mode, we must generate dynamic HTML.
   *
   *    4.) If the request is a server action, we must generate dynamic HTML.
   *
   * These rules help ensure that other existing features like request caching,
   * coalescing, and ISR continue working as intended.
