🏗️ Architecture Overview

Core Components

Component	Description
Background Service Worker	Manages state, injection, hotkeys, storage, and communication
Inject Script	Injected into pages, captures audio via `captureStream()`, processes with Web Audio API
Popup Interface	Quick controls for EQ, presets, volume, and bass
Window Interface	Full-featured standalone window with all controls

Audio Processing Pipeline

Capture: HTMLMediaElement.captureStream() → MediaStream
Source: AudioContext.createMediaStreamSource() → MediaStreamAudioSourceNode
Analyzer: AnalyserNode for spectrum visualization
Gain: GainNode for volume control (0% – 800%)
Hard Mute: Secondary GainNode for instant silence at 0%
Bass: BiquadFilterNode (lowshelf @ 100Hz, ±12 dB)
10-Band EQ: 10 BiquadFilterNode (peaking filters, Q=1.0)
Compressor: DynamicsCompressorNode to prevent clipping
Fade: GainNode for smooth transitions
Output: Connected to AudioContext.destination
