## Shared Components Usage

```
MediaUploadBox
├── Used by: ImageForm, ImageVideoForm
├── Variants: Image upload, Video upload, Cover upload
└── Props: type, uploadedFile, onUpload, onRemove, label?, required?

TeammatesSection
├── Used by: ImageForm, ImageVideoForm
├── Controlled by: topicConfig.requiresTeammates
└── Props: teammates[], onAdd, onRemove, onChange

FormInput
├── Used by: ImageForm, ImageVideoForm
├── Variants: Single line, Multiline (textarea)
└── Props: label, value, onChange, placeholder, multiline?, rows?
```

## Config → Component Mapping

```
Topic 1 (تخته سیاه)
├── mediaType: "image"
├── requiresTeammates: true
└── formComponent: ImageForm → Shows image + teammates

Topic 2 (نیمکت)  
├── mediaType: "both"
├── requiresTeammates: true
└── formComponent: ImageVideoForm → Shows tabs + teammates

Topic 3 (دفترچه یادداشت)
├── mediaType: "image"
├── requiresTeammates: false
└── formComponent: ImageForm → Shows image only

Topic 4-9 (Other topics)
├── mediaType: "image"
├── requiresTeammates: varies
└── formComponent: ImageForm → Configured per topic
```

---

## Adding New Topic (Flow)

```
Step 1: Choose Form Type
   │
   ├── Need video? → ImageVideoForm
   ├── Just image? → ImageForm
   └── Custom? → Create new form
   │
   ▼
Step 2: Update topicConfig.ts
   │
   ├── Add topic object
   ├── Set mediaType
   ├── Set requiresTeammates
   └── Set formComponent
   │
   ▼
Step 3: Done! ✅
   │
   └── SubmitChallengePage automatically uses new config
