A page constructed for the browser but not yet stored anywhere else is shown as a translucent page with no border.
# State
Gray background pages provide information such as search results or new page creation dialogs.
# Transition
An explicit fork from the fork button will copy the ghost page to permanent storage as a White Origin or Yellow Local page.
Edits to a ghost page will be stored as a Yellow Local page since edits alone cannot create a page at the origin.
HERE HERE --> White Origin HERE --> Yellow Local
