ActivityHeatmap

Day × time grid of rounded cells for "when is my audience online". Cells wear the bright brand-cyan sequential ramp by intensity; the Less→More scale legend names the ramp and every cell carries a hover/focus read-out with the exact share. Pair with ComboChart when the answer needs an hourly curve instead of a week grid.
