/**
 * The LibreOffice-backed {@link @nhtio/adk/batteries/media/contracts!MediaEngine}: document,
 * spreadsheet, and presentation conversion via the `soffice` binary.
 *
 * @module @nhtio/adk/batteries/media/engines/soffice
 *
 * @remarks
 * Document conversion is the one capability in the media battery with no mature
 * cross-environment equivalent, so this engine is binary-backed by design. It composes the
 * two BYO runtime contracts: a {@link @nhtio/adk/batteries/media/contracts!BinaryExecutor}
 * runs the invocation (bundled: `execa_executor`) and a
 * {@link @nhtio/adk/batteries/media/contracts!ScratchWorkspace} exchanges bytes with it
 * (bundled: `fs_workspace`). The executor and workspace must agree on path visibility —
 * that pairing is the consumer's composition decision.
 *
 * One engine, one capability kind: the conversion matrix is declared as convert capability
 * groups (each format silo converts within itself plus to PDF/HTML; PDF converts to
 * html/txt/docx/odt). The spreadsheet group covers ODS/legacy-xls to xlsx — what used to be
 * a separate "normalize" engine is just an edge in the matrix.
