/*
 * Marker web pages: "Night match".
 *
 * The world is a floodlit court after dark, the same one the app draws:
 * board-green ground, chalk-white line work, and the app's live green as the
 * single accent (the serve ball, the active row, the primary action).
 * One family, Archivo (variable width + weight, self-hosted, SIL OFL):
 * condensed for headings like a scoreboard, normal width for reading,
 * expanded for small navigational labels.
 *
 * Layout: a calm reading column inside a frame the world owns (masthead with
 * a court line, floodlit opener, a contents rail where the ball marks your place).
 *
 * Contrast on --night: chalk 16.8:1, chalk-dim 9.4:1, live 8.8:1.
