/* rougeworks.dev
   The site is themed from the Rouge Works logo: navy ink, river red and map
   paper, with the River Rouge topo map from the app's Field Guide theme
   (EchoCam/Theme.swift, surface .topo). Thenscape's pages add
   `class="thenscape"` to <body>, which swaps in the app's Kodachrome colours
   (EchoCam/Themes.swift) inside the same layout. */
