+    Public Directory Assets
+        Static assets from public/ directories with automatic cache-busting:
+        '/public/sneat/css/core.css'
+        '/public/sneat/js/helpers.js'
+
+        These resolve to files in any public/ directory in rsx/. Resolution

+
+PUBLIC ASSET INCLUDES
+    Bundles can include static assets from any public/ directory with
+    automatic cache-busting via filemtime().
+
+    SYNTAX
+        Prefix paths with /public/ in bundle includes:
+
+            'include' => [
+                '/public/sneat/css/core.css',
+                '/public/sneat/js/helpers.js',
+            ]
+
+    RESOLUTION
+        Path "sneat/css/demo.css" resolves to first match across all public/
+        directories in manifest. Resolution cached in Redis indefinitely.
+
+        Searches:
+            rsx/public/sneat/css/demo.css
+            rsx/app/admin/public/sneat/css/demo.css
+            rsx/theme/public/sneat/css/demo.css
+            ... (all public/ directories)
+
+    OUTPUT
+        CSS: <link rel="stylesheet" href="/sneat/css/demo.css?v={filemtime}">
+        JS:  <script src="/sneat/js/helpers.js?v={filemtime}" defer></script>
+
+        The filemtime() call executes on each page render, providing fresh
+        cache-busting timestamps without rebuilding bundles.
+
+    ORDERING
+        Public assets output with CDN includes, before compiled bundle code.
+        Order preserved as listed in bundle definition:
+
+            1. CDN CSS assets
+            2. Public directory CSS
+            3. Compiled bundle CSS
+            4. CDN JS assets
+            5. Public directory JS
+            6. Compiled bundle JS
+
+    AMBIGUITY ERRORS
+        If multiple files match the same path, compilation fails:
+
+            RuntimeException: Ambiguous public asset request:
+            'sneat/css/demo.css' matches multiple files:
+            'rsx/public/sneat/css/demo.css',
+            'rsx/theme/public/sneat/css/demo.css'
+
+        Solution: Use more specific paths or rename files to avoid conflicts.
+
+    CACHING
+        - Path resolution cached in Redis indefinitely
+        - Cache validated on each use (file existence check)
+        - Stale cache automatically re-scanned
+        - filemtime() executes on each page render for cache-busting
+
+    RESTRICTIONS
+        - Only .js and .css files allowed
+        - Must start with /public/ prefix
+        - Files must exist in a public/ directory
+        - No PHP files allowed (security)
