/* Layout: one page read top to bottom. A drawn cross section of the island (land above, reef below) opens it,
   then what we keep, the three projects already running, the three that come next (with a working help button),
   and ways to help. One bright theme on purpose (Jerome prefers light drafts for Yodchai's sites).
   One type family only, Anuphan (Thai + Latin), never stretched. */
