As an occasional user of shr (mainly when viewing HTML parts in Gnus)
who frequently messes with window width and face height, I'm very much
interested in better visual-line-mode integration.  Also intrigued by
outline-mode support.  So closely following this thread, and
enthusiastically thanking Rahguzar for tackling this 👏

Don't know if I have anything insightful to say re. the patches.  Idly
wondering if '(null shr-fill-text) ⇒ (visual-line-mode)' is the right
control flow; e.g. maybe

  (a) shr-fill-text could be set to 'visual as a more explicit hint for
  major modes, or

  (b) major modes should grow new user options: e.g. eww-wrap-method ∈
  {fill, visual}; 'visual would tell modes to set shr-fill-text to nil &
  enable visual-line-mode.

There are already plenty of user knobs at the shr level though, so maybe
no need to overthink this.
