Moved the editor section to the top of the page, right after the features section in commit 884f879.

@copilot the UI and theme color are ugly. Need to improve UI and align with existing theme color

Updated the UI to align with the site's theme in commit 3b8328f. The changes include:

• Removed the purple gradient background, now using var(--ifm-color-emphasis-100) like other sections
• Updated shadows and borders to be more subtle and use theme colors
• Adjusted typography to match site style (2.25rem title, 1.1rem description)
• Cleaner, more minimal design that integrates seamlessly
