/**
 * Pure page-operation step implementations for PDFs: select, split, merge, reorder.
 *
 * @remarks
 * Internal sibling of the `@nhtio/adk/batteries/media` entry. Implemented with `pdf-lib`
 * (optional peer, lazily imported) on in-memory bytes — no binaries, cross-environment.
 * Phase 0 covers PDF inputs; PPTX slide operations and DOCX section operations join in the
 * sheet/slides/doc phases, sharing these verb ids with format dispatch.
