+
+### Patch Changes
+
+- a990973: Add support for @position-try global at-rule
+
+  Added support for CSS `@position-try` at-rule (CSS Anchor Positioning Level 1) in Compiled's cssMap API. The `@position-try` at-rule defines named fallback positions for CSS Anchor Positioning and is now correctly handled as a global at-rule, similar to `@keyframes`.
+
+  **What changed:**
+
+  - Added `'position-try'` to the ignored at-rules list in `packages/css/src/plugins/atomicify-rules.ts`
+  - This ensures `@position-try` rules are emitted globally without atomification or component scoping
+  - Both nested and flat syntax styles are supported:
+    - Nested: `'@position-try': { '--name': { ... } }`
+    - Flat: `'@position-try --name': { ... }`
+
+  **Browser support:**
+
+  - Chrome 125+ (May 2024)
+  - Firefox 131+ (Oct 2024)
+  - Safari 18.2+ (Dec 2024)
+
+  **Example usage:**
+
+  ```typescript
+  const styles = cssMap({
+    arrowBlockStart: {
+      '@position-try --ds-arrow-block-start': {
+        positionArea: 'block-start',
+        margin: 0,
+        marginBlockEnd: 'var(--ds-arrow-size, 8px)',
+      },
+    },
+  });
+  ```
+
+  **Note:** Type support for `@position-try` was already present via csstype 3.2.3 (added in #1867). This change completes the implementation by ensuring the CSS transformation correctly handles it as a global at-rule.
