/* Kodza — Progress
   A bar or a ring, driven by data-value (0–100; leave it out for "we don't know yet"). The
   percentage rolls digit by digit like an odometer; at 100 it gives way to a tick that draws
   itself, and the label rolls to data-done if you set one. Without a value, a segment slides
   along the bar (or an arc turns around the ring). Change data-value from your code, the
   component follows. Everything is tuned with the --kz-progress-* variables. */
