/*!
 * styles.css — China Arrival Kit.
 *
 * The visual idea is an official arrival form: warm paper, hairline rules,
 * crop marks at the corners, machine data set in a monospace face, and one
 * vermilion accent that behaves like an ink stamp. The dark theme is the same
 * sheet read under a desk lamp at night — same rules, same ink, inverted.
