/* Vicaya Studio website
   Layout: a canvas-like site. Pages sit on a faint dot grid like the app's flow canvas;
   content runs in one 1120px column with a 20px gutter. Indigo is the brand accent (from
   AccentColor), amber is the single highlight (the lit tile in the app icon), and the six
   role colours are used only where they mean what they mean in the app. */
