/**
 * `slides.*` step implementations: native PPTX container mutation via JSZip + targeted XML
 * edits, on in-memory bytes.
 *
 * @remarks
 * Internal sibling of the `@nhtio/adk/batteries/media` entry. Ported from the source server's
 * slides adapters (regex-over-zip XML surgery — no XML parser dependency). PPTX is mutated
 * natively; ODP inputs are normalized to PPTX through the configured `convert` engine first,
 * degrading to a readable failure when none is configured. All implementations are
 * cross-environment (jszip operates on Uint8Array).
