/* Phase 6: Enter the Ashram (/darshan; includes/views/darshan.php, assets/js/darshan-lite.js, darshan-loader.js, darshan.js).
   Two layers: the photo sequence (every scene a section: photographs, title, description, About this place, Sit here,
   Continue) that works alone, and the walk-through (html.dn-walk) where the scene fills the screen and the text floats
   over it. Tokens from tokens.css; Divine Dark Temple and both light palettes read correctly. Phones first. */
