Typewriter catalog preview starts outside the frame #3248

Describe the bug

The Typewriter component preview scales the demo text beyond the 1920×1080 composition, so the animation begins and ends with text clipped outside the left and right frame edges.

Reproduction

1. Open the Typewriter component.
2. Play the preview.
3. Observe the first and last characters extending beyond the frame.

Source reproduction: registry/components/typewriter/demo.html

Expected behavior

The full hyperframes add typewriter line and caret remain inside the preview frame throughout playback.

Actual behavior

The demo uses scale(2.8), which makes the rendered text wider than the composition and clips both sides.

Environment

Hosted HyperFrames Catalog and the current main branch (3670e9a92). Reproduced in Chromium and the local HyperFrames render pipeline.
