Sticker previews: clip to cut line, never bake effects into source files

When building review boards for die-cut sticker artwork that carries 3 mm bleed, clip each preview to the CutContour path instead of showing the raw PNG; otherwise the bleed looks like a rendering glitch and reviewers think the file was edited. Keep all drop shadows, halos and white edges as presentation-only layers in the board, and verify staged copies against sources with cmp so you can prove the files are byte-identical. Record print scale as metadata (a TARGETS list applied at print time) rather than resampling the artwork, and keep text above about 6 pt at the chosen scale for vinyl legibility.
