    "Packaged scripts retain full Acornima syntax validation and defer Jint function/declaration analysis to first use. Ordinary network/user evaluation is unchanged.",
    "Reuse engine-independent identifier binding names and immutable static property keys; count AST nodes during parsing instead of walking the entire tree a second time.",
    "Initialize the final file/language/model once through trusted primitive host data, and select the final theme before creating the model. File data is never parsed as JavaScript source.",
    "Cache website C# tokenization by model identity and version. Avoid per-line whole-model reads and prefix concatenation, and reuse exact-version tokens for readback.",
    "Keep the original official Monaco 0.52.2 core, website highlight.js grammar and palette bytes; no worker services or CLR access were enabled.",
    "Merge upstream branded Console/Desktop boot animation and rebuild/revalidate both editions before delivery."
