Roadmap
Blocks are bands and features are boxes. A box sits in the wave it can start in: wave 1 is everything nothing blocks, wave 2 is everything waiting on wave 1. Hover a box to see what it waits on. Progress is counted from the tickets, never stored.
Left to right is what has to finish first. Top to bottom is which block claims it. Tasks, bugs and spikes are not on a roadmap: they are under a feature.
