Why is this change being made?

Previously, the fixed-width iframes caused layout issues; they overflowed the content container and introduced horizontal scrolling on smaller screens. This fix ensures the embeds scale with the container, preserving readability and layout consistency across devices.

How was this tested?

• Verified rendering locally by viewing the updated markdown/HTML page.
• Confirmed that embeds resize correctly with different viewport widths.
• No visual regressions observed in desktop view.
