Interop for Mandelbrot Grid Calculations

This document defines a cross-language interop structure for Swift, Rust, and JavaScript to compute and color Mandelbrot sets efficiently.

Basic Number Types

Integer Types

• Swift: Int32
• Rust: i32
• JavaScript: number (64-bit float, but used as an integer)

Floating-Point Types

• Swift: Double (8 bytes, 64-bit)
• Rust: f64
• JavaScript: Float64Array

Calc Grid Input Structure

Your colors are stored as f64 values ([f64; 3]). Many PNG libraries expect u8 values ([u8; 3]), so we must scale the colors correctly.
