\begin{tablenotes}\footnotesize\item Level and Slope: level and slope change at 2022-12 (first p: level, second p: slope). Interrupted-time-series estimates on the log monthly count of works with the category as primary label, event month 2022-12, HAC p-values (Part IV); placebo p: share of baseline-period pseudo-events whose slope t-statistic exceeds the observed one (Section~\ref{sec:m-placebo}); Bai--Perron: break months selected by BIC (results/econometrics/breaks.csv, which also reports PELT and BOCPD dates).\end{tablenotes}
