labelize

Cut a new labelize release: bump Cargo.toml version, add CHANGELOG section, update Cargo.lock, run tests, commit, push tag, and draft GitHub Release. Use when: releasing a new version, bumping version, cutting a release, publishing to crates.io, updating changelog for release, tagging a release, creating a GitHub Release draft.

Auto-detect high-diff ZPL labels, extract problematic elements into standalone ZPL files, and iteratively fix rendering logic until diff drops below 1%. Use when: label diff is too high, need to reduce rendering differences, want automated fix cycle, batch fix all labels.

Diagnose and fix ZPL rendering differences by auto-learning from official Zebra documentation. Use when: rendered label doesn't match expected output, pixel diff is too high, barcode looks wrong, text positioning is off, graphic elements are misplaced, golden test fails, rendering bug, wrong render, visual mismatch, diff threshold exceeded.

Look up ZPL command specifications from the official Zebra Programming Guide. Use when: implementing ZPL commands, debugging ZPL parsing, verifying parameter defaults, checking command interactions, fixing rendering that doesn't match expected ZPL behavior, understanding barcode or font or field or graphic command semantics.
