Add bleed margins to a PDF for commercial print shops that trim — extends the page size by the bleed amount on each side and shifts content to the new center. Most office digital printing does NOT need this; use only when sending to a print shop. Triggers on phrases like "add bleed", "add 3mm bleed", "prep for trim".
Generate a matching-size cover page with a title (and optional subtitle, author, date) and prepend it to a PDF. Triggers on phrases like "add a cover page", "prepend a title page", "make a cover for this PDF".
Overlay a diagonal text watermark (DRAFT, PRIVATE, CONFIDENTIAL, etc.) at 45° across every page in light red (or user-specified color), at low opacity so body text remains readable. Triggers on phrases like "add a DRAFT watermark", "stamp PRIVATE on every page", "watermark this PDF".
Burn a permanent footer label into every page of a PDF — CLIENT CONFIDENTIAL, PRIVATE, FAMILY DISTRIBUTION, DRAFT, EMBARGOED UNTIL ..., or custom text. User can choose font and size. Renders a PNG preview to verify layout before committing. Triggers on phrases like "add a CONFIDENTIAL footer", "burn in a footer", "stamp 'embargoed until' across the bottom".
Convert a color PDF to grayscale (black-and-white) for monochrome digital printing — saves toner and avoids color-mismatch issues. Triggers on phrases like "convert PDF to grayscale", "make it black and white", "remove color from PDF", "monochrome PDF".
Bundle one or more print-ready PDFs into a single "print job" folder with a manifest, ready to hand to a digital printer or share with collaborators. Triggers on phrases like "create a print job", "bundle these PDFs", "make a job folder for the printer".

Re-process a PDF so every font used is fully embedded.
Non-embedded fonts trigger printer-side substitution. Common substitutions (Arial → Helvetica → Liberation Sans) cause subtle width changes that ripple into reflowed lines, broken tables, and shifted page breaks.

Look at the emb and sub columns:
yes yes — fully embedded subset (fine).yes no — fully embedded full font (fine).no no — NOT embedded (problem).Ghostscript with -dEmbedAllFonts=true -dSubsetFonts=true re-runs the PDF through pdfwrite and embeds whatever it can find on the system.

Every row should show emb=yes. If any are still no, the font isn't installed on the system — install via fc-list / apt install, then re-run.
