 # Diagram Tools
 
+Diagram Tools is a local, script-free editor for bounded flowchart, sequence,
+class, state, entity-relationship, mind-map and timeline sources. It provides
+line diagnostics, reusable examples, accessible outlines, pan/zoom, local
+source import/export, normalized JSON, inert SVG and local PNG export. Mermaid
+directives, styling, click handlers and external resources are never executed.
+
 Diagram Tools is a GPL-3.0-or-later local text/visual editor with an independent safe Mermaid-like subset for flowchart/graph, sequence, class and state diagrams. It produces deterministic SVG, a local 2× PNG, syntax diagnostics, scroll/drag pan, 25–300% zoom and an accessible textual outline.
 
-Supported syntax is deliberately small: node declarations/shapes and four edge styles; participants/messages; class declarations/members/relations; state nodes/transitions. Directives, clicks, styles, scripts, HTML and remote assets are rejected. Caps: 50,000 characters, 2,000 lines, 200 nodes, 500 edges, 2,400 px layout edge and 20 megapixel PNG.
+Supported syntax is deliberately small: node declarations/shapes and four edge
+styles; participants/messages/notes; class declarations, bounded member blocks
+and relations; labelled state nodes, start/end boundaries and transitions; ER
+attributes/relations; hierarchical mind maps; and timeline sections/events.
+Directives, clicks, styles, scripts, HTML and remote assets are rejected. Caps:
+50,000 characters, 2,000 lines, 200 nodes, 500 edges and a 20 megapixel PNG;
+large vector canvases remain scrollable instead of clipping model content.
 
 Run `npm ci`, `npm run check`, `npm run test:browser`, then `npm run package:release -- --force`.

 # Architecture
 
-`core/diagram.ts` parses one fixed grammar into nodes, edges and line diagnostics, then lays it out deterministically as escaped SVG. Sequence diagrams use lifelines; other modes use a bounded grid. React shows the last successful SVG after errors and delegates PNG rasterization to a local canvas.
+`core/diagram.ts` parses fixed, bounded flowchart, sequence, class, state, ER,
+mind-map and timeline grammars into nodes, edges and line diagnostics, then lays
+them out deterministically as escaped SVG. ER attribute blocks and sequence
+notes, class member blocks and labelled state transitions/boundaries become
+inert model data; directives, click handlers, remote resources and styling
+commands are rejected rather than interpreted. Layout dimensions are derived
+from the bounded model rather than clipping nodes to a fixed viewport.
+
+React retains the last successful SVG after errors, imports/exports source and
+the normalized JSON model, and delegates optional PNG rasterization to a local
+canvas. Generated SVG contains only application-owned geometry and escaped
+text.
