Thank you for the review! I've addressed all the feedback:

Sentence case fixes:

• Capitalized HTML and MDX acronyms in settings UI text
• Capitalized dropdown theme options (Auto, Light, Dark)

Async function fixes:

• Removed async keyword from resolveVideoPath and resolveImagePath functions as they don't use await

All changes have been pushed and the build passes successfully.

Fixed the remaining sentence case issues - changed 'MDX' back to lowercase 'mdx' in descriptions to match the existing style throughout the settings file. HTML remains uppercase as it's a formal acronym.
