/*
 * All of the site's styling.
 *
 * The palette is the app's own (src/theme/theme.ts): paper and ink by day, the
 * same near-black the scoreboard uses by night, and the ball yellow as the one
 * accent. Dark mode follows the reader's system setting, because somebody
 * opening this from the court at nine in the evening should not get a flash of
 * white.
 *
 * No web fonts: the system stack paints with the first frame, and a request to
 * fonts.googleapis.com would hand every visitor's IP address to Google before
 * they had agreed to anything.
