Overview

Patches Rails layout files to insert ‘react_bundle_tag` after the `javascript_include_tag` call, or before `</head>` as a fallback.

Supports .html.erb, .html.haml, and .html.slim. Skips files that already contain ‘react_bundle_tag`. Atomic write: backs up original before writing.

Usage:

ReactManifest::LayoutPatcher.new(config).patch!
