Blog cards on /blogs showed only the primary author as "By @username". For multi-author posts, co-authors were invisible and no author info was linked to GitHub profiles.

Changes Made

src/pages/blogs/index.tsx

• Drop primaryAuthor — iterate all authors instead
• Replace single <div className="card-avatar"> with <div className="card-avatar-stack"> rendering up to 3 circular avatar <Link>s, each pointing to the author's GitHub
• Replace "By @handle" text with comma-separated full name links:

  {authors.map((author, idx) => (
    <React.Fragment key={author.id}>
      {idx > 0 && <span className="card-author-sep">, </span>}
      <Link href={author.githubUrl} className="card-author-handle" target="_blank" rel="noopener noreferrer">
        {author.name}
      </Link>
    </React.Fragment>
  ))}

src/pages/blogs/blogs-new.css

• .card-avatar-stack — flex row with -8px left margin on stacked avatars for overlap effect; hover scales focused avatar to front (z-index: 10)
• .card-author-names — flex wrap container with overflow: hidden to prevent long names from escaping card bounds
• .card-author-sep — muted comma separator, no extra spacing

Dependencies

None.
