## Overview

#### Purpose and entry point
This is a small server-rendered banking operations application. `app.py` is the application entry point and likely owns HTTP routing, request handling, and template rendering. The UI is delivered as HTML rather than a separate frontend application.

#### Web runtime and presentation boundary
The application runs in Python, with dependencies declared in `requeriments.txt`. Server-generated views reside under `templates/`; `templates/base.html` is the shared page shell/layout boundary, while feature pages extend or are rendered within that structure.

#### Customer information flow
Customer-oriented requests are represented by `templates/customer_info.html`. The controller logic in `app.py` is expected to gather or receive customer data, select this template, and pass view-model values into it. The boundary between request/controller code and presentation is the template context supplied by `app.py`.

#### Transaction submission flow
`templates/transaction_form.html` is the input surface for banking transaction data. A typical flow is: browser loads the form → user submits a request to a route in `app.py` → server validates/processes the submitted values → server returns an operation/result view. Form fields and request payloads are the main untrusted-input boundary.

#### Banking operations and results
`templates/banking_operations.html` represents the banking-operation workflow or its resulting state. `app.py` is the central orchestration point connecting transaction input, operation logic, and result rendering. No separate domain package, persistence layer, API client, queue, or database infrastructure is visible in the repository tree, so any such behavior—if present—is likely embedded in `app.py` or absent.

#### Key architectural components
1. Application/bootstrap and route handlers: `app.py`.
2. Dependency/runtime declaration: `requeriments.txt`.
3. Shared HTML layout: `templates/base.html`.
4. Customer-information view: `templates/customer_info.html`.
5. Transaction capture view: `templates/transaction_form.html`.
6. Banking operation/result view: `templates/banking_operations.html`.

#### Operational boundaries
The repository appears to be a single-process Python web application with server-side templates and no visible external-service integration. The main control path is HTTP request handling in `app.py`, followed by rendering one of the templates. Important boundaries are browser form input, route-level processing, and server-rendered HTML output.

Main entry points: [`app.py`](https://github.com/ramirezlzrga/banco/blob/main/app.py) (Routes and operations), [`templates/customer_info.html`](https://github.com/ramirezlzrga/banco/blob/main/templates/customer_info.html) (Customer information), [`templates/transaction_form.html`](https://github.com/ramirezlzrga/banco/blob/main/templates/transaction_form.html) (Transaction form), [`templates/banking_operations.html`](https://github.com/ramirezlzrga/banco/blob/main/templates/banking_operations.html) (Banking operations result)

- [Routes and operations](https://github.com/ramirezlzrga/banco/blob/main/app.py): Python application · Handles requests, validates submitted values, and renders template contexts. · `app.py`

### HTML templates

Server-rendered browser views.

- [Shared page layout](https://github.com/ramirezlzrga/banco/blob/main/templates/base.html): HTML layout · Shared shell for feature pages. · `templates/base.html`
