Public, read-only page over the ned-collector energy schema: latest-hour
mix and per-source utilization, generation vs consumption with CO2
intensity (day/week/month/12 months/all years), NED forecast, gas storage
by year and per site, and gas-fired power share vs storage fill.
Incomplete hours (sources not summing to the NED total) are left out and
partial days/months/years are marked.
