/* /scary-minds: the Scary Minds landing page, on Halloween night.
   Colors come from the app's default Moon Boo theme (docs/DESIGN.md): ink
   (#2E2347) on a peach sunset (#FFF0DC to #FFC48F) with pumpkin-orange tile
   edges (#FF9454) in light mode, and pale ink (#F2F4FF) with periwinkle
   (#AFC2FF) on a navy night (#152E56 to #060C1A) with gold edges (#E0B83A) in
   dark, and the app's purple candy (#9B5DE5). The 3D scene adds the moon, the
   hill and the six characters of the app's six themes (scary-minds.js). The
   app sets every tile, button and number in the system serif (New York), and
   so does the page. It follows the system's light and dark mode. */
