Document parsing & data extraction pipeline
Performs non-destructive manipulation of Portable Document Format (PDF) binary object streams in accordance with ISO 32000-1 and ISO 32000-2 (PDF 2.0). Operates on underlying PDF cross-reference tables (XRef), catalog dictionaries, page trees (/Pages), and content streams via pdf-lib and PDF.js. Implements symmetrical margin cropping based on existing CropBox / MediaBox origin coordinates [x, y], executes 90-degree page rotations, merges/splits page trees, and preserves AcroForm interactive form fields, annotations, and bookmarks.

File size & structure constraints
Operational constraints and validation boundaries: Nonempty PDF below 100 MB. Arabic assigned numbers 1–999999999, Roman 1–3999, including the last number. Templates are one line, at most 120 characters, using {n}, {last}, {page}, {total}; unsupported tokens or glyphs are rejected. Standard fonts support WinAnsi text, not CJK or emoji. Labels use an 18-point inset in displayed coordinates; an oversized label or invalid visible box is rejected. Existing content may overlap; no automatic blank-space detection. No original content, page boxes or rotation is removed. Native reader/print and near-limit memory remain unverified.
