/* Krishna Mail — admin stylesheet.
 *
 * Hand-written and dependency-free. A CSS framework would be one more thing to
 * update and one more thing to override; this is a few hundred lines that can be
 * read in one sitting and does everything the panel needs.
 *
 * Dark by default: this is an operations tool that people leave open, and the
 * mail-specific statuses (sent / bounced / suppressed) read better against a dark
 * ground than pastel pills on white.
