• Draft comment:
  Add a newline at end of file for consistency.
• Reason this comment was not posted:
  Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 10% vs. threshold = 50%
  While having a newline at end of file is a common convention, this is exactly the kind of thing that should be handled by ESLint/Prettier automation rather than manual code review comments. Our standards specifically mention that ESLint and Prettier should be set up to enforce code style rules automatically.
  The comment is technically correct about a common convention. Maybe enforcing this manually is important if the automation isn't set up yet?
  No - our standards explicitly state that ESLint/Prettier should be set up to handle code style rules automatically. Making manual comments about things that should be automated doesn't add value.
  Delete this comment as it addresses a code style issue that should be handled by automated tooling rather than manual review.

  Avoid using direct DOM manipulation with innerHTML in React—this can bypass the virtual DOM and pose XSS risks. Instead, use state to conditionally render the <iframe>.

Avoid using innerHTML injection in the onClick handler. Use component state for conditional rendering of the iframe to prevent potential XSS risks and ensure React-managed DOM updates.

[ellipsis-dev]

Enhance accessibility by adding attributes (e.g., role='button', tabIndex=0) to the clickable video container.

Suggested change

	<div
	<div role="button" tabIndex={0}
