## Overview

`IndicatorSystem` renders **screen-space HUD markers** for world-space actors. It handles the full pipeline — from projecting a 3D world position to screen coordinates, to clamping out-of-view indicators to the screen edge with a directional arrow.

Key capabilities:

* **Data Asset configuration** — every visual and behavioral aspect is driven by `UIndicatorSetupConfig`
* **Pluggable Setup Actions** — configure indicators by composing small, reusable action objects (Blueprint and C++)
* **Multiple projection modes** — project from a component pivot point, its bounding box, or the whole actor bounding box
* **Screen-edge clamping** — indicators that move off screen lock to the edge and show a directional arrow
* **Distance-based visibility** — configurable min/max view distances
* **Overlap prevention** — indicators avoid drawing on top of each other
* **Fully Blueprint-accessible** — everything is exposed to Blueprint

        └── Projects each descriptor's world pos → screen pos

```

## Quick Start

1. Create a **`UIndicatorSetupConfig`** data asset — configure your actions
2. Add **`UIndicatorManagerComponent`** to the target actor — assign the config
3. Add **`UIndicatorLayer`** widget to your HUD — covers the full screen
4. Implement **`IActorIndicatorWidget`** on your indicator widget — receive descriptor data
