/**
 * Initialize red links call-to-action
 *
 * Upon clicking a red link, show an interstitial CTA explaining that the page doesn't exist
 * with a button to create it, rather than directly navigate to the edit form.
 *
 * Special case T201339: following a red link to a user or user talk page should not prompt for
 * its creation. The reasoning is that user pages should be created by their owners and it's far
 * more common that non-owners follow a user's red linked user page to consider their
 * contributions, account age, or other activity.
 *
 * For example, a user adds a section to a Talk page and signs their contribution (which creates
 * a link to their user page whether exists or not). If the user page does not exist, that link
 * will be red. In both cases, another user follows this link, not to edit create a page for
 * that user but to obtain information on them.
 *
