Mandelbrot Set

The iconic boundary of infinite mathematical complexity.
It is the set of complex numbers c for which the function f_c(z) = z² + c does not diverge when iterated from z = 0.
This ASCII renderer maps the escape-time algorithm directly to characters. The deep black interior (`#2b2b1a`) represents coordinates that never escape to infinity, while the glowing orange and bright green borders map the turbulent chaos at the boundary.
