/* Mirror Garden — one stylesheet.
   Concept: a calm garden at dawn (light) and under an indigo night sky (dark).
   Soft rounded cards, gentle shadows, the Sun's warm orange and the Moon's
   indigo as the two accents; each garden tints the page while you play in it.
   Type: the system's rounded face where there is one; tabular numbers. */
