Example 03 Fig05 — stimulus effect surfaces:
  Replace 3D plot_wireframe (gray) with 2D pcolormesh (viridis colormap),
  matching MATLAB's mesh() with view([90 -90]) top-down heatmap rendering

Example 01 Figs 01/03 — plotInvGausTrans ACF panel:
  Reduce marker size from 4.0 to 3.0 so individual scatter dots are visible
  across the full lag range (~550 lags), matching MATLAB's dot-scatter style

Example 02 Fig02 — GLM coefficient error bars:
  Change error bars from 1x SE to 1.96x SE (95% CI) matching MATLAB;
  switch marker from "." to "o" at size 8 for visibility

Example 05 Figs 03/05/06 — start/finish markers:
  Change filled blue/red circles to unfilled (open) circles with
  markerfacecolor="none" and markeredgewidth=2, matching MATLAB

Example 03 Fig01 — CIF legend:
  Add label="$\lambda_i$" and legend(loc="upper right") to match MATLAB

LaTeX rendering:
  Fix legend labels in Example 03 Fig06 from unescaped strings to proper
  raw f-strings with $\lambda$ mathtext wrapping
