Set-piece volume: stacked area

A stacked area chart of set-piece attempts over match time, binned into 15-minute windows, one band per type – a volume read of the match: which restart types made up the bulk of the traffic in each phase of the game, and whether that mix shifted. Different from plot_match_timeline()’s individual dots (unaggregated) and plot_set_piece_value_flow()’s cumulative line (one signed value, not a volume breakdown by type).
