**Título:** ``` [FEATURE] Native tablet viewport preview mode in preview_screenshot tool ```

Problem Statement

The preview_screenshot tool truncates the viewport when using the tablet preset (768x1024).
The bottom portion of the screen is cut off in the screenshot, even though the browser
renders it correctly. This makes it impossible to visually verify tablet layouts without
using workarounds like JavaScript DOM inspection.

The mobile preset (375x812) works correctly and captures the full height.
The tablet preset should behave the same way.

Proposed Solution

Fix the tablet preset (768x1024) to capture the full viewport height in screenshots,
matching the behavior of the existing mobile preset.
