City Monitor

A temperature is not a number, it is a trajectory. The same 28.4 °C an hour before peak is a buy after 26.9 / 27.7 / 28.4 and a sell after 29.1 / 28.8 / 28.4 — and the level alone cannot tell you which. Each card is the glance; open one for the trace, the measured climb profile, every bucket's price over 48 hours, and the ladder.
