Activity columns on a labeled y-axis, wearing the brand-cyan sequential ramp by value (light→dark), with quiet rug marks under the slots you posted in and a black anchor + chip on the best slot. One bar per time slot at a uniform step — never mixed bin widths. Hover or focus a bar for its read-out — a posted slot's read-out includes that post's engagement, never a second axis.
