 * The LeaseWeb Usage and System panels.
 *
 * A LeaseWeb VPS has no provider API behind it, so these two panels render
 * figures read off the box itself: vnStat's transfer history, and a system
 * report gathered over SSH. Everything else on the VPS console is shared with
 * the Linode and DigitalOcean panels and styled in client.css — only the parts
 * with no equivalent there live here.
 *
 * Colours reuse the console's existing palette (slate on near-black, the same
 * inbound/outbound pairing the Network panel uses) so the new tabs read as part
 * of the same screen rather than a bolt-on.
