presentation/properties/narrative
Structured storyline describing the deck's arc and beats. Resolves to the 'id' of a 'narratives' catalog record. Accepts two forms: - String shorthand for the common case: 'narrative = "classic-story"'. Accepts a bare id (lowercase kebab-case), an HTTPS URL pointing at a record file, or a 'pkg:' reference to a locally-installed package. - Object form for inline overrides or fully custom narratives: 'narrative = { id: "classic-story", beats: [...] }'. The object shape mirrors https://openpresentation.org/schema/opf-narrative/v1 (sans '$schema'), so a library record and an inline narrative are interchangeable. Resolution order: inline catalogs.narratives.records[] → catalogs.narratives.source → default catalog at https://www.pptx.gallery/narratives. Unknown ids produce a validation warning, not an error. Deck-level concerns that aren't part of the storyline (audience, tone, takeaway, duration) live as siblings on the presentation root rather than inside the narrative object.
