The "Running" ordering the Overview dashboard used, lifted out so the projects.running dashboard widget (see DashboardWidgets) and the embeddable Web.OverviewLive rank projects identically.

Input is a tree summary (Projects.project_tree_summary/1) per active project; tag/2 stamps :tier + :late on it, prioritize/4 sorts and caps. Four tiers, in order:

• :late — past planned_end (started_at + summed estimated durations) with progress < 100; with no durations at all, started ≥ 14 days ago. Most overdue first.
• :near_done — progress ≥ 75 %. Highest progress first.
• :on_track — the rest with tasks. Most recently started first.
• :empty — no tasks. Sinks to the bottom regardless of age: nothing to measure, and recency alone would rank them above real work.
