Subtitle and Caption System Design

## ROLE
You are a game UI designer specializing in subtitle and caption systems. You've studied the best implementations (The Last of Us Part II, Forza Horizon 5, Spider-Man 2) and understand both technical requirements and player needs.

## OBJECTIVE
Design a subtitle and closed caption system for [GAME TITLE] that exceeds current industry standards and serves deaf, hard-of-hearing, and all players who prefer text-based audio information.

## TASK

### Subtitle System
- Speaker identification: character name with consistent color coding per speaker
- Font selection: sans-serif, high-legibility typeface (similar to OpenDyslexic option)
- Size options: minimum 5 sizes from small to extra-large (default should be readable at 10ft from TV)
- Background: adjustable opacity letterbox behind text (0%, 25%, 50%, 75%, 100%)
- Color options: text color customization, high contrast presets
- Position: adjustable vertical position (bottom, middle, top)
- Line count: maximum 2-3 lines visible at once, proper pacing
- Speed: adjustable display duration, option to hold until manually dismissed

### Closed Caption System (Beyond Subtitles)
- Environmental sounds: [footsteps approaching], [door creaking], [explosion in distance]
- Music cues: [tense music plays], [music intensifies], [music fades]
- Directional indicators: arrows or compass showing sound source direction
- Intensity indicators: volume represented by text size or formatting
- Emotional tone: [whispering], [shouting], [sarcastically], [nervously]
- Off-screen events: describe sounds from sources not visible on screen
- Ambient descriptions: [rain pattering on roof], [crowd murmuring]

### Visual Sound Radar
- On-screen sound indicator: radial display showing active sound sources
- Distance representation: icon size or opacity based on proximity
- Sound type icons: distinct symbols for footsteps, gunfire, speech, music, alerts
- Threat prioritization: hostile sounds highlighted differently from ambient
- Customizable position and size: player chooses where the radar sits
- Opacity and visibility: adjustable transparency, option to show only in combat

### Technical Implementation
- Localization support: subtitles must work across all supported languages
- Text wrapping: intelligent line breaks that preserve meaning
- Timing synchronization: subtitles match audio with configurable lead time
- Cutscene vs gameplay: different presentation modes for cinematic and interactive moments
- Multiplayer: distinct styling for different players' voice chat
- Performance: subtitle rendering must not impact frame rate

### Testing Requirements
- Readability testing at standard TV distances (6ft, 10ft, 15ft)
- Testing with deaf and hard-of-hearing players
- Colorblind testing for speaker identification colors
- Performance testing: no frame drops during subtitle-heavy scenes
- Localization testing: verify layout works for all languages including RTL

## OUTPUT FORMAT
Subtitle system design document with UI mockups, technical specifications, customization options matrix, and testing checklist.

## CONSTRAINTS
- Subtitles must be on by default with a prominent first-launch prompt
- Support at minimum: English, Spanish, French, German, Japanese, Portuguese, Chinese, Arabic
- Text must remain readable during fast-paced gameplay
- System must handle overlapping audio sources gracefully
- Comply with CVAA requirements for video game communications
