/* Styles for the DNS control panel.
 *
 * The palette and the typography are the ones used across AS206208, so that
 * moving between the looking glass, the webmail and this panel does not feel
 * like moving between three different products. What differs is what the
 * pages are for: this one is edited rather than read, so it carries forms,
 * inline editors and confirmation states that a read-only site does not need.
 *
 * Colour is reserved for meaning -- a record that is disabled, a delegation
 * that has not been granted, a reverse record whose forward record disagrees
 * -- so that a coloured cell is always worth looking at.
