Object And Type Reference
Composition
- Type:
object - Required fields: none
- Purpose: Portable dynamic composition. Slide fields override the resolved layout. Nested groups arrange their children independently, inheriting only minFontSize and overflow. Explicit promoted regions retain their positions.
| Field | Required | Type | Notes |
|---|---|---|---|
mode | no | enum:auto | grid | row | column | auto chooses a grid from available space and content; grid uses columns; row and column use one horizontal or vertical track. |
columns | no | integer | Column count for grid. In auto mode this caps the number of columns. |
gap | no | number | Space between cells as a fraction of the container short edge (canvas at slide root). Default 0.03333333333333333. |
padding | no | number | Inset as a fraction of the container short edge. Default 0.08 on a slide, 0 inside a group. |
weights | no | array<number> | Relative track sizes: columns for row/grid/auto, rows for column. Omitted tracks have weight 1; extra weights are ignored. |
minFontSize | no | number | Minimum readable text size in reference pixels at a 720-pixel canvas short edge. Default 16. Overflow is diagnosed when text cannot fit at this size. |
overflow | no | enum:warn | error | warn returns diagnostics for content that does not fit; error rejects layout. Content is never silently removed. Default warn. |

Narrative
- Type:
object - Required fields: none
- Purpose: Structured storyline used by AI to shape generated content. Mirrors the OPF Narrative Template record at https://openpresentation.org/schema/opf-narrative/v1 (sans '$schema'), so a library record and an inline narrative are interchangeable. Narrative declares the deck's intended story arc; slides may opt into beats via Slide.beat. The narrative does not constrain slide structure validators warn on drift (orphan slides, unused beats) but never error. Slides are the source of truth; narrative i...
