Key highlights of the appPlantUML diagrams on Confluence pages: UML class, sequence and C4 from text, drawn inside Atlassian with no PlantUML server

PlantUML, C4 and UML from text
Type PlantUML with C4 built in, nomnoml or Mermaid, and the diagram appears on the page. No PlantUML server: everything is drawn inside Atlassian.
Annotate the model by hand
Circle what changes, add notes and arrows, paste screenshots. Excalidraw's hand-drawn style shows that a design is under discussion.
Design docs that stay correct
Every macro is its own diagram, page copies get their own copy, the last 10 versions are kept, and PDF/Word export includes the drawing.
