### 1.1 Application Architecture
The entire system is divided into four layers: the presentation layer, the communication layer, the service layer, and the data layer. The dark blue part in the diagram represents the functions and authorizations procured for this project, implementing the IT application innovation and transformation for the supporting H5 video service functions. The red part in the diagram represents the existing system functions.
Below is the architecture:

Figure 4.3 System application architecture

1. - Presentation Layer: The front-end application uses HTML5 web pages and is built with the Vue framework, responsible for page display.
2. - Data Layer: Customer account opening business data is submitted to the middle platform for temporary storage. After approval, the business middle platform submits the customer's account opening request to the account system

### 1.2 dKey Business Processes
The main business processes of the non-face-to-face account opening system are as follows:
1）Login Verification: Verification is performed using the customer’s mobile phone number and verification code.
2）Selecting a Business Department: By default, the nearest business department is recommended based on location information. Customers can also manually select a business department.

### Steps to reproduce

from docling.document_converter import DocumentConverter

source = "list_document.docx" # document per local path or URL
converter = DocumentConverter()
result = converter.convert(source)
print(result.document.export_to_markdown()) # output: "## Docling Technical Report[...]"

the result misses "**Key Business Processes**" ([url]( #url))
