61. front_panel: product name/descriptor + the ONE claim that wins the 3-second shelf scan against shelf_set (the front panel is a billboard, not a brochure) + flag word count vs. panel size.
72. back_panel: the romance copy (2–3 sentences of why-we-exist in brand voice), usage/ritual suggestion, and the trust block (certifications on file only).
83. claims_check: every claim vs. reg_elements and substantiation — [COMPLIANCE REVIEW] flags for anything regulated (natural, organic, made-in, nutrient claims).
94. hierarchy_spec: reading order with relative size weighting (name → claim → variant → size).
105. shelf_test: describe how the front panel differs from the two nearest competitors — if the answer is "color", the copy hasn't done its job.
