/**
 * MoonPhase calendar component styles.
 *
 * Mobile-first: base rules are for phones (one month card per row, a compact
 * seven-column day grid). Container queries add columns as the calendar's own
 * width grows, so it adapts to any template layout; viewport media queries only
 * adjust spacing. Every selector is scoped to .moonphase-calendar.
