## v2.0.19 — Slideshow to video requires a theme

Slideshow-to-video now requires a slideshow theme so every generated slide shares one design system.

### Changed

- **Breaking:** `POST /v1/workflows/slideshow-to-video` requires `slideshowThemeEntityId`. Create a `SLIDESHOW_THEME` entity with `POST /v1/entities`, attach a reference image, and pass that `vg_enti_...` id. Omitting the field returns `400`.

> HTTP API with TypeScript and Python SDKs for generating image, video, and audio assets with VideoGen.
