Investigate layout configurations (layout: standard/split_screen and imagePosition: left/right) for the Editorial Carousel section across types, MCP server, backend, admin UI, and renderers.

## Investigation State
- **Explored paths**: 
  - packages/types/index.ts
  - apps/mcp-server/section-toolkit.ts
  - apps/backend/src/routes/pages.ts
  - apps/admin/src/components/page-builder/EditorialCarouselForm.tsx
  - apps/spa/src/components/DynamicEditorialCarousel.tsx
  - apps/website/src/components/dynamic/DynamicPageRenderer.tsx
- **Key findings**: 
  - Schema extension needs `layout` and `imagePosition` as optional keys.
  - MCP tool properties configuration must expose both options.
  - Backend validation handles the schemas seamlessly via `safeParse`.
  - The Admin UI requires form elements that update local payload state.
  - The client and website renderers require grid columns `35%` / `65%` and mobile stacked behavior using CSS grid/order styling.
- **Unexplored areas**: none (all files in scope explored)

## Key Decisions Made
- Layout controls and logic designed for complete backwards compatibility.
- CSS order property determined to be the cleanest approach for mobile layout stacking.
