   GENERATION 3 ACADEMY — the public site.
   Deliberately NOT the game's deep-ocean theme. This is warm, light and
   architectural: parchment, antique gold, tilework teal.

   All ornament is geometry, arch and pattern — the Islamic visual tradition —
   drawn as SVG. No depiction of any living being anywhere, which is a hard
   project rule and also why nothing here is a photograph.
