/**
 * Field coverage is derived from `pptx-viewer-core`'s
 * `ELEMENT_FIELD_KIND`/`SLIDE_FIELD_KIND` (the same canonical inventory the
 * viewer's `collaboration-sync.ts` allowlists derive from), so this codec
 * automatically tracks every field `PptxElement`/`PptxSlide` declares
 * instead of drifting out of sync with a hand-maintained list. Wire-format
 * prefixes stay long-form (`_textStyle`) here versus the viewer schema's
 * short-form (`_ts`) - the two Y.Doc layouts are intentionally NOT
 * interchangeable, only the field *coverage* is required to match.
 *
 * `asset`-kind fields (large binary payloads like `mediaData`) are simply
 * embedded as scalars here rather than routed through a separate asset map:
 * this codec does one-shot bidirectional file<->Y.Doc conversion, not a
 * live P2P transport, so there's no repeated-write cost to avoid.
