Projects on board alert(3.6.2)

Of those escalating, how many have crossed into the higher "board alert" threshold. These are the projects that warrant explicit sponsor attention, not just team-level firefighting. A week measuring fewer than two of the three signals is left unscored and cannot be counted here. A value shown as "—" means the read returned nothing or the figure could not be measured. It is never to be read as a zero: a measured zero is printed as a zero, and a card with no figure also carries no accent color, because a tint is a judgment about a number and there is no number to judge. The date range selects whether the portfolio snapshot appears at all, while the figures themselves are still taken from each project's latest complete scored week. The week in progress is not counted: only complete weeks enter this number, so it does not change as the current week fills.
