# 0003 — Preview Rendering

- **Date:** 2025-09-02
- **Status:** Accepted

## Decision

- Full Preview: responsive, **JSON pretty**, **PDF inline**, HTML via sandboxed iframe.
- Table thumbnails: compact preview elements.
- Single `loadPreviewInto(container, ctx)` governs all rendering and Blob lifecycle.

## Consequences

- Consistent behavior across formats.
- Safer HTML rendering (no inline script execution due to iframe sandbox).
