/*
 * WebWolf design tokens ("Veillée").
 *
 * One table under three skies. The palette is the same warm, bistre-tinted
 * family throughout; only lightness and chroma move with the hour:
 *
 *   dusk   home, lobby, card reveal   the default, set on :root
 *   night  the night phase            darker still, and the ink dims with it
 *   day    discussion, vote, result   pale paper: every phone brightens at once
 *
 * Night sits below the usual 12-18% band for a dark surface on purpose. A
 * table full of face-up phones must not glow while eyes are meant to be shut.
 *
 * styles.css references these by name. It never writes a colour or a font of
 * its own, nor a gap or padding that is off the scale below; a value that is
 * missing gets added here first. One-off dimensions - how wide a card is drawn,
 * how long a toggle's track - stay beside the thing they size.
