Adjust Countdown behavior and UI: reduce default milestone to 10000, parse target dates as NZ local time (explicit +13:00) and prevent negative remaining seconds. Rework progress calculation to measure percent complete from page load to target, clamp percent to 0-100, and add days to the hours display. Format milestone display with seconds and fix time-scale used for the "time until first pixel" computation (use elapsed in seconds). Comments added to clarify timezone handling.
