+## [1.9.0](#1.9.0) - 2026-03-07
+
+### Fixed
+
+Fix issue where studio shows malformed color semantic token with token name
+
+### Added
+
+Add support for `*Css` prop convention in JSX components.
+
+Any JSX prop ending with `Css` (camelCase, e.g. `inputCss`, `wrapperCss`) is now treated as a style prop during static
+extraction, enabling compound component patterns like:
+
+```tsx
+function Comp(props) {
+  const { inputCss, wrapperCss, children } = props
+  return (
+    <styled.div css={wrapperCss}>
+      <styled.input css={inputCss} />
+      {children}
+    </styled.div>
+  )
+}
+
+// Usage - styles are statically extracted
+const usage = <Comp inputCss={{ color: 'red.200' }} wrapperCss={{ display: 'flex' }} />
+```
+
+This works in both `all` and `minimal` JSX style prop modes, with no configuration needed.
