Popup, step 1

1. "Merge page(s) into this page (New York) "
   • (selected by default, so the user can immediately click Continue)
2. "Merge page(s) into
   Type here...
   • Displays an inline input field where the user must insert exactly 1 page, say, Canada. (should also be chosen if the target doesn't yet exist)
3. "Merge pages without specifying a direction"

Popup, step 2

• User is required to type at least 1 page and a maximum of a couple hundred pages
• If Talk pages are given as a source or as a destination, remove "talk:" and keep the pagename

Quickchecks

• ensure destination page(s) DOESN'T include the source page or source!==dest
• ensure BOTH articles exist/ALL source pages exist
• ensure destination page exists if `Unclear...` is unchecked
• if OK, go to Popup, step 3

• SOURCE PAGES: ["AAA", "BBB", "CCC", "DDD", etc.
• DESTINATION PAGE: "New York"

Text that says "Discussion will be created on Talk:[DISCUSSIONPAGE]"

• [DISCUSSIONPAGE] is autofilled with New York if user chose option 1
• [DISCUSSIONPAGE] is autofilled with Canada if user chose option 2, EXCEPT if Canada doesn't exist. In that case, let the user type it.
• [DISCUSSIONPAGE] is autofilled with Talk:First page of the input box in step 2 if user chose option 3

Two input fields: (section_title, merge_rationale)

1. Section title:
