The blog post author card had three non-interactive elements (avatar, name, @handle) alongside a separate "GitHub" button — only the button linked to GitHub. All three should be independently clickable links to the author's profile.

Changes Made

src/theme/BlogPostItem/Footer/index.tsx

• Avatar: Wrapped <img> (and fallback initial div) in <Link to={githubUrl}> when githubUrl is available
• Author name: Changed from <p> to <Link> when githubUrl is available — preserves existing visual style
• @handle: Decoupled from the joined metaItems string; rendered as a standalone <Link> inline with the remaining plain-text date/read-time

// Before: all three were non-interactive
<p className={styles.authorName}>{authorName}</p>
<p className={styles.authorMeta}>{metaItems}</p>  // "@handle • date • read time" — plain string

// After: avatar, name, and handle are all GitHub links
<Link to={githubUrl} className={styles.authorAvatarLink}>...</Link>
<Link to={githubUrl} className={styles.authorName}>{authorName}</Link>
<p className={styles.authorMeta}>
  <Link to={githubUrl} className={styles.authorHandleLink}>{authorHandle}</Link>
  {META_SEPARATOR}{metaDateAndTime}
</p>

src/theme/BlogPostItem/Footer/styles.module.css

• .authorAvatarLink — display: block to preserve circular layout; subtle opacity on hover
• .authorName — text-decoration: none at rest, underline on hover; explicit color to prevent browser link color override
• .authorHandleLink — inherits color, underline on hover only

Dependencies

None.
