## Legend

- `pN-compare.png`: reference | Safe-PDF | diff. Diff colors: red = ink missing in Safe-PDF, blue = extra ink in Safe-PDF, magenta = hue differs, orange = same hue but different intensity (shape), yellow = anti-aliasing or 1 px displacement (tolerated), pale blue hatching = annotation area (not compared), gray = matching.
- Region classes: missing_ink / extra_ink = one renderer drew nothing there; color_shift = same shapes, different color; reshaped = both drew but glyph shapes or geometry differ (often font substitution); offset = same content shifted by a few pixels.
- `pN-regionK.png`: reference | Safe-PDF crops of region K, enlarged.
- Region pixels are `[x0, y0, x1, y1]` from the top-left. Page space is PDF user space `[left, bottom, right, top]`.
- Draw `#n` is the n-th Safe-PDF backend call on the page. Bounds are device pixels after clipping, and draws are listed tightest fit first.
- `pN-content.txt` lists the page's content stream operators. `report.json` has full backtraces and worker stderr.
