/* Deliberately tiny and first in the head: the app's stylesheet is large, and until it parses the
   browser paints its own default canvas - a white frame on every refresh, which reads like a
   camera shutter. This paints the right background immediately.
   color-scheme also tells the browser which way to draw scrollbars, form controls and overscroll
   before the app's CSS arrives. The values mirror the tokens in src/index.css. */
