+- **Trailing Whitespace Patch**: Custom templates injected into the Sign module canvas can sometimes incur trailing QWeb whitespace `Text` nodes. This crashed Odoo’s native `target.lastChild` reference when opening templates or dragging new fields. This module implements frontend Javascript patches (`sign_backend_patch.js`) over Odoo's native `insertAdjacentHTML` method to instantly trim whitespace nodes on injection. This ensures robust reliability across Odoo updates without touching core source code.
