@shekhirin should merge once prod site is ready
Lower CHART_POINT_TARGET from 750 → 300 and add a MAX_METRIC_ROWS (15,000) hard cap on the metric samples query. Mix workload benchmark runs produce many more metric series (due to diverse label combinations across quantiles and node types), and the cartesian product of series × points was exceeding the Cloudflare Worker's 128 MB memory limit, causing error 1101 crashes. 300 points per series is still sufficient for smooth chart rendering, and the 15k row cap ensures the total response stays well within the Worker's memory budget even for the heaviest runs.
