/* s-lights.css: the twelve morning lights and the layer for two (Us), loaded after app/ui.css.

   A ritual of twelve mornings. Each light opens on the sky of the hour with the string of twelve
   hung across it, in the palette's red, amber, green and gold: the bulbs up to that morning glow,
   that morning's glows most, the rest are clear glass. The first time a light opens on a phone,
   its own bulb comes on and the glow runs along the wire. Akshay's notes are letters: cream card
   stock, his navy ink, his wax seal, which cracks in two when Krista opens one; what she sends back
   stays on the paper. Every color comes from design/tokens.css; this file only mixes them. */
