 ## Executive Summary
 
-Templates provide reusable **chrome configurations** (background, header, footer) bundled with **isolated style systems** for consistent slide presentation. Templates are like Keynote master slides - they define the visual frame and default styling, while users continue writing markdown content using `@section`/`@column` directives normally.

Templates are like Keynote master slides - they define the visual frame and default styling, while users continue writing markdown content using `@section`/`@block` directives normally.
 
-**Key Principle:** Templates control the **decorative layer** (chrome + styling), not the content layout. The existing `@section`/`@column` system remains unchanged.
