lib/diagram-engine/ — layout and rendering
--------------------------------------------------------------------------------

The declarative layout algorithm (bottom-up measure, top-down place, sibling
size equalisation) and the mxCell/style emission in `lib/diagram-engine/layout.ts`
and `lib/diagram-engine/render.ts` are derived from drawio-ai-kit:

The XML→tree reverse parser (`lib/diagram-engine/parse.ts`), the style-marker
scheme (`markers.ts`), the structural-operations layer (`operations.ts`) and the
invisible-container approach that replaces that project's "phantom" nodes are
original to this repository.

lib/diagram-engine/data/aws-stencils.json — stencil catalog
--------------------------------------------------------------------------------

A name→style map for the mxgraph.aws4 stencil family, generated from
drawio-ai-kit's `catalog/aws.json`, which in turn was generated from the draw.io
shape index published by jgraph:

The style strings are reproduced verbatim from that index. They reference the
official AWS Architecture Icons, which are trademarks of Amazon Web Services and
are NOT covered by this repository's licence. Their use is governed by the AWS
Architecture Icons terms:

The catalog contains stencil *names and style strings* only — it does not embed
any AWS icon artwork. draw.io supplies the artwork at render time.
