 * One stylesheet for the whole site.
 *
 * Paper and ink: wault replaces a drawer of thermal receipts, so the page is
 * the colour of the paper and the type is set to be read at a glance on a
 * phone, in a shop, with the receipt in the other hand. Green means covered,
 * amber means a deadline is near, red means it has passed — and every one of
 * those is also said in words, never by colour alone. Dark is designed, not
 * inverted, and follows the system. Controls are at least 48 px tall.
