/*
 * Online analog clock (/shizhong/) - page-exclusive styles.
 *
 * The dial is drawn with one element and its two pseudo-elements: a
 * repeating-conic-gradient paints the 60 minute ticks, each numeral paints its
 * own longer hour tick, and the centre cap sits above the hands.  Every size
 * is derived from --kiv-clock-size, so the whole clock scales down on small
 * screens instead of being transformed, blurred, or clipped.
