Wiki renders pages with visual clues as to where they have been found.
# Halo
Pages that have been retrieved from some place permanent are rendered opaque white with a possible colored border indicating where they were found. The page flag hover will elaborate on this information for the curious or colorblind.
A blue border marks a 'remote' page, one that is from some ordinary site other than the origin.
A green border marks a 'plugin' page that might exist to deliver the plugin or to explain how you might use it on your own pages.
A yellow border marks a 'local' page stored privately in the browser but still identified as part of the origin site.
A white border (no border) marks a page retrieved from the origin server, as expected.
# Ghost
Interactions can add pages to the lineup that don't exist in any permanent place. These are rendered transparently which might just show as gray on plain backgrounds. Ghost pages intend to be useful on their own. Some provide items that are useful dragged from their initial ghostly existence on to pages worth keeping.
