[Graph Mindset] Border and Padding

[tomsmith8]

Task:

The borders and spacing around the UI components (transcript card, video player, and timeline) are currently inconsistent and exceed the intended 20px padding. We need to ensure that all borders, paddings, and margins are correctly set to 20px to maintain a clean, uniform layout.

Acceptance Criteria:

• All outer borders (left, right, top, bottom) around the video player and transcript panel are exactly 20px.
• The timeline scrubber area should have a consistent 20px spacing from adjacent elements.
• Check for any overlapping or misaligned borders and correct them to follow the 20px standard.
• Confirm no visual regressions occur in related UI components.
