+### Node Styling
+
+Add shape-level styling directly to nodes with inline `@key:value` attributes:
+
+```excalidraw
+(Start) -> [Enter Credentials @fillStyle:hachure @backgroundColor:#a5d8ff] -> {Valid?}
+{Valid?} -> "no" -> [Show Error @backgroundColor:#ffc9c9 @strokeStyle:dashed] -> [Enter Credentials]
+```
+
+For repeated or shared nodes, define defaults with an `@node` block:
+
+```excalidraw
+@node [Enter Credentials]
+  fillStyle: solid
+  backgroundColor: #a5d8ff
+
+(Start) -> [Enter Credentials @fillStyle:hachure] -> {Valid?}
+```
+
+Supported node style keys:
+
+- `fillStyle`: `solid`, `hachure`, `cross-hatch`
+- `backgroundColor`
+- `strokeColor`
+- `strokeWidth`
+- `strokeStyle`: `solid`, `dashed`, `dotted`
+- `roughness`
+- `opacity`
+
+Precedence rules:
+
+- `@node` blocks provide defaults for matching nodes
+- inline node attributes override block values
+- repeated references to the same node merge explicit style properties with later values winning per property
+
