Suggestion: The frontmatter references ./images/post-image.png, but no such file exists under this post directory (or the shared blog images folder), so image resolution will fail when this MDX is processed. Add the image at the referenced path or update the image field to an existing asset path. [possible bug]
Severity Level: Major ⚠️
❌ Blog post hero or header image fails to load.
⚠️ Blog listing cards may show broken or missing thumbnail.Steps of Reproduction ✅
1. Open `content/blog-post-2026-07-05/web-performance-in-2026-a-practical-guide.mdx` and
observe the frontmatter at line 7: `image: './images/post-image.png'`, which declares a
relative image path for this blog post.
2. Inspect the repository for the referenced asset by searching for `post-image.png`
(e.g., via Glob pattern `**/post-image.png` rooted at `/workspace/frontend-junction`); no
matching file exists anywhere in the codebase, confirming the frontmatter path points to a
non-existent image file.
3. Build or run the site so this post is rendered; any component or page template that
reads the `image` frontmatter to display a header/preview image for
`web-performance-in-2026-a-practical-guide.mdx` will generate a URL for
`./images/post-image.png`, which results in a broken image (404 or missing asset) because
the underlying static file is absent.

Validate the correctness of the flagged issue. If correct, How can I resolve this? If you propose a fix, implement it and please make it concise.
Once fix is implemented, also check other comments on the same PR, and ask user if the user wants to fix the rest of the comments as well. if said yes, then fetch all the comments validate the correctness and implement a minimal fix

The Velite config in velite.config.ts uses pattern: 'blog/**/*.mdx', which only picks up files under content/blog/. This file lives in content/blog-post-2026-07-05/ and will never be indexed, built, or rendered on the site. It needs to be moved to content/blog/web-performance-in-2026-a-practical-guide.mdx (or another path matching the blog/** glob) to be included.

The frontmatter specifies image: './images/post-image.png', but no images/ subdirectory or post-image.png file was included in this PR. Velite processes s.image() as a pipeline asset — a missing file will cause a build error when the file is eventually placed in a scanned directory.
| ```typescript | ||
| // Example of modern web performance pattern | ||
| function useModernPattern() { | ||
| // Implementation example | ||
| return { | ||
| apply: () => { | ||
| console.log("Applying modern web performance pattern"); | ||
| } | ||
| }; | ||
| } | ||
| ``` | ||
|
|
||
| ### 2. Common Pitfalls to Avoid | ||
|
|
||
| - **Ignoring performance**: Always measure before optimizing | ||
| - **Over-engineering**: Start simple, add complexity when needed | ||
| - **Not following conventions**: Stick to established patterns in your codebase | ||
|
|
||
| ### 3. Best Practices | ||
|
|
||
| 1. Start with the basics before moving to advanced patterns | ||
| 2. Test your implementations thoroughly | ||
| 3. Document your code for future reference | ||
| 4. Keep performance in mind throughout development | ||
|
|
||
| ## Real-World Example | ||
|
|
||
| Here's a practical example you can adapt for your projects: | ||
|
|
||
| ```typescript | ||
| // Real-world application example | ||
| interface Props { | ||
| data: string[]; | ||
| onUpdate: (value: string) => void; | ||
| } | ||
|
|
||
| function Component({ data, onUpdate }: Props) { | ||
| return ( | ||
| <div> | ||
| {data.map(item => ( | ||
| <button key={item} onClick={() => onUpdate(item)}> | ||
| {item} | ||
| </button> | ||
| ))} | ||
| </div> |

The code examples are inert stubs (console.log("Applying modern web performance pattern"), a generic button list component) and the prose contains no concrete performance techniques — no Core Web Vitals, no LCP/INP/CLS guidance, no bundling, caching, or rendering strategies. The existing post at content/blog-post-2026-06-11/web-performance-in-2026-a-practical-guide.mdx (also titled "Web Performance in 2026") covers real case-study content on ISR, SVG sprites, and useMemo. This new post reads as an AI-generated template that was committed before the actual content was written.
Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!

content/blog-post-2026-06-11/web-performance-in-2026-a-practical-guide.mdx already exists in the repository with the exact same filename. If both directories are ever brought under the Velite scan pattern, their slugs will collide and one will silently overwrite the other in the generated index.
