/**
 * A Staves document as a Mermaid flowchart, for anywhere Mermaid renders (GitHub, GitLab, Notion, docs).
 * Tracks are subgraphs, jobs are nodes, handoffs are edges labelled with what passes, and a gate is a
 * rhombus placed on the track of whoever answers for it. Tasks fold into the job they belong to, so the
 * chart shows the jobs a person would name. Provenance is summarised in one legend line.
