Diagram tabs

Tabs run across the top of a published blueprint and are the reader's main navigation. The first is always a diagram.

Adding

Add tab in step 1 offers the six kinds. The choice is fixed once content exists in the tab.

Naming

Tab names are the labels on the strip. Short nouns work: Logical, Physical, Runtime, Data. Avoid restating the blueprint title in every tab.

A tab strip is easy to miss. If a later tab holds something essential, say so in the first tab's prose.

Ordering

Drag to reorder. The first tab must remain a diagram: the editor will not let you drag a prose tab into first position.

Engines

Each diagram tab has its own engine, and a blueprint can mix them: a Vellum context diagram, a Mermaid sequence diagram, and an imported draw.io network diagram in one document. draw.io, Excalidraw and Mermaid covers the non-Vellum engines.

Limits

There is a hard ceiling on tabs per blueprint. If you are close to it, split the content into several blueprints in a portfolio, or move it into a folium.
