# Mandelbrot Deep Zoom

> Interactive browser-based Mandelbrot deep-zoom explorer with guided navigation, high-precision perturbation rendering, animated palettes, music-reactive visualization, and Fractal Echo effects.

## Main pages

- / — interactive Mandelbrot explorer (WebGL canvas)
- /about.html — features, rendering approach, controls, and technical overview
- /privacy.html — local audio and privacy behavior

## Features

- Mandelbrot deep zoom with pan, pinch, wheel, and tap gestures
- Smart, Guided, and Fixed zoom paths for autopilot navigation
- perturbation / reference-orbit rendering for deep magnification
- multiple color palettes including Breathe animated palette
- Fractal Echo afterimage trails
- music-reactive visualization (Breathe Sync and Full Spectrum modes)
- local MP3/WAV loading (client-side only)
- Basic Controls presets and Advanced Controls for fine-tuning
- explicit deep-link sharing via Copy share link (hash URLs)

## Technical notes

- Single-page static site: one HTML file with inline CSS and JavaScript
- WebGL 2 fragment shaders for escape-time rendering
- CPU-side high-precision fixed-point coordinates (BigInt) for deep zoom math
- switches from GPU fast path to emulated double and perturbation shaders by zoom depth
- reference orbit computed on CPU, sampled in GPU for perturbation rendering
- Web Audio API for client-side music analysis; optional default demo track or local file upload
- no backend, accounts, analytics, or server-side audio upload
- preferences stored in browser localStorage; URL is not rewritten during normal exploration
