WDSX — developer guide

This guide is a stub. Content is coming as the docs settle.

Things this guide will cover:

• Package layout — core (shared types), importer (WDS → JSON/SVG/MD), viewer (SvelteKit app).
• The importer CLI — running it against your WDS data dump.
• Viewer data model — tree, search index, diagram bundles.
• SVG diagram interactions — hotspots, label scaling, print layout.
• PWA + offline caching.
• Building the Docker container.

In the meantime, the project README has the layout + build basics.
