1.0
Separate identity-critical details from adaptable detail
Mark the logo shape, wording, character features, colors, and proportions that must not change. Then identify decorative texture, tiny lines, gradients, and secondary detail that may be simplified to suit the finished size and process.
This distinction prevents a proof from silently changing the brand while allowing production engineers to flag details that cannot be expressed clearly in metal, enamel, molded PVC, resin, or paint.
