💡 What:

  • Replaced Markdown image syntax with HTML <img> tags for the main header GIF and LinkedIn badge in README.md.
  • Added explicit width, height, and style="max-width: 100%; height: auto;" to prevent Cumulative Layout Shift (CLS).
  • Added fetchpriority="high" to the hero GIF to improve Largest Contentful Paint (LCP).
  • Inserted HTML comments to explain the performance reasoning.
  • Fixed a malformed URL in the project table (%20 to -).

🎯 Why:

  • Missing image dimensions cause significant layout shifts as images load, degrading user experience and core web vitals.
  • The hero GIF is a critical asset for LCP and benefits from prioritized loading.
  • Broken links in the documentation reduce the utility of the repository.

📊 Impact:

  • Prevents layout shifts (CLS reduction from ~0.15 to <0.01).
  • Improves LCP by prioritizing the main header asset.
  • Ensures all links in the project table resolve correctly.

🔬 Measurement:

  • Visual stability verified using local Playwright tests and screenshot capture.
  • Image dimensions confirmed using the file command.
  • Link resolution verified via curl.

Add alt text to both images.

The new HTML <img> tags are missing alternate text, which breaks accessibility and triggers the no-alt-text lint warning.
