How It Works
 
6D Shape Vectors
 
Each ASCII character is represented as a 6D vector capturing how it fills its cell.
					Six sampling circles in a staggered 2×3 grid measure density at different positions.
 
Nearest Neighbor Matching
 
For each cell in the image, we sample a 6D vector and find the character whose
					pre-computed shape vector is closest in Euclidean distance.
 
Global Contrast
 
Normalizes the sampling vector to [0,1], applies an exponent to crunch darker values,
					then denormalizes. Exaggerates shape differences for better character picks.
 
Directional Contrast
 
External sampling circles detect edges by reaching into neighboring cells.
					When a neighbor is lighter, it pushes the internal value down, sharpening boundaries.
