Each tile iterates z_n+1 = op(z_n, c) from z₀ = 0, coloring by escape speed over c ∈ [−4, 5] × [−3, 3]i. Area and box-counting dimension come from Session C (300×300, max-iter 80). Green tiles are the "complete" family (the structural rule T26–T28: exp(+z) always gives exact completeness). Amber tiles are the "approx" family (exp(−z); approximately complete but not exactly). The N-variants replace ln(+c) with ln(−c) = ln(c) + iπ; on the complex viewport this shifts the image but preserves geometry, so the paired areas and dimensions match exactly.
