/* Runlines website. Plain CSS, no framework.
   Tokens from Runlines/Core/Theme.swift ("Velvet house"): plum-black house,
   one tungsten-amber spotlight, warm paper for script text, jade for "off book",
   curtain rose for "shaky". Dark is the brand, so the site is dark only.
   Serif (New York / ui-serif) for anything that reads like a printed script;
   system sans for interface text. 14px radius, the app's corner. */
