## Overview

This package appears to be the top-level area for the application’s currency converter entry point. Based on the available child documentation, its role is intentionally narrow: it boots the desktop UI and hands control to the Swing layer. In other words, this package is the launch surface for the application, not where conversion rules or business logic live.

Because the index found only one documented child module, this area currently reads as a very thin bootstrap layer. The system design appears to favor keeping startup separate from the UI implementation itself, which makes the package easy to understand and low-risk to change.

## Sub-module Guide

### `converter`

The `converter` sub-module contains the executable entry point. Its documented class, `CurrencyConverter`, exposes `main(String[] args)` and immediately schedules UI creation with `SwingUtilities.invokeLater(...)`.

Relationship-wise, this module is the bridge between the JVM process and the application window:

- it receives startup control from the Java runtime,
- it defers execution to Swing’s event dispatch thread,
- and it instantiates the UI class that appears to contain the real application experience.

This means `converter` does not implement conversion behavior itself. Instead, it coordinates startup and hands off to the UI layer, so any feature work beyond launching the app likely belongs elsewhere.

## Key Patterns and Architecture

### Thin bootstrap entry point

The clearest pattern in this package is separation of concerns. `CurrencyConverter` is deliberately small and only performs startup orchestration. That suggests an architectural preference for:

- keeping the executable entry point minimal,
- placing Swing construction on the correct thread,
- and isolating UI setup from application launch mechanics.

### Event-dispatch-thread startup

The child documentation shows a standard Swing startup flow: `main(...)` calls `SwingUtilities.invokeLater(...)`, which then constructs `UI`. This appears to be an intentional concurrency safeguard, since Swing components should be created and manipulated on the event dispatch thread.

### One-way startup flow

The module currently has a one-directional relationship:

- `CurrencyConverter` starts the application,
- Swing schedules the UI,
- the UI layer takes over.

There is no evidence of shared state, domain services, or cross-module callbacks in the available index. That makes this package function more like a launch coordinator than a business subsystem.

## Dependencies and Integration

### Internal integration

The only documented internal dependency is the UI layer referenced by the child module documentation. The converter package appears to integrate with:

- `[com.github.blaxk3.ui](src/main/java/com/github/blaxk3/ui/UI.java)` — the application window and main interface appear to be created there.

### Platform integration

The package depends on standard Java Swing startup behavior:

- `javax.swing.SwingUtilities` — used to move UI creation onto the event dispatch thread.

### What is not present in the index

The code analysis for `com.github.blaxk3` did not identify additional indexed source files, classes, methods, or cross-module relationships. That means there is no documented evidence here of:

- backend services,
- persistence,
- exchange-rate integration,
- or domain model classes.

So the available documentation suggests a self-contained desktop startup layer rather than a broader application platform.

## Notes for Developers

- `CurrencyConverter.main(String[] args)` is the application entry point; if startup behavior changes, this is the first place to look.
- `args` is currently unused. If command-line options are added later, this is the natural hook for parsing them.
- UI construction should continue to happen on the Swing event dispatch thread.
- The package currently appears to be a bootstrap layer only. If new business logic emerges, it will likely belong in a separate module instead of being added here.
- Because the index did not surface additional children or source files, treat this overview as a high-level structural summary rather than a complete inventory of implementation details.
