   The session "foyer". Cream paper background, oversized serif masthead,
   a marqueed event ticker, and two tiles that visually preview the two sites'
   distinct aesthetics (light pinboard vs dark lab) before the user clicks.
   --------------------------------------------------------------------------
   Palette: CQU primary (Dark Green #1f4040 / Hero Green #c7db5c / White)
            with Pale Green #dfe99a for atmosphere, and Plum #a85b8b as a
            single off-brand accent on Site 02 to push contrast further.
   Type:    Georgia (display, matches the flyer) + Tahoma (body) +
            ui-monospace stack for the Site 02 code preview.
