Write a reusable author bio block for a multi-author blog

We have five contributors writing for our blog and want every post to end with
a consistent author bio box. Here's the info for one of them, to use as the
template case:

Name: Elena Vasquez
Title: Senior Editor
Bio: "Elena has covered small business finance for eight years and previously
edited the money section at a regional paper."
Headshot: elena-vasquez.jpg
Links: Twitter/X @elenavwrites, personal site elenavasquez.com

[replace with your own contributor's name, title, bio, photo, and links]

Design this as a block structure meant to be saved as a synced (reusable) pattern
so every author gets the identical layout:

1. Use a `wp:group` with a border-top and some top padding to visually separate
   the bio from the article content above it, then a `wp:columns` block inside
   with two columns: a narrow one for the headshot, a wide one for the text.
2. In the narrow column, a `wp:image` for the headshot, alt text set to the
   person's full name and title ("Elena Vasquez, Senior Editor"), cropped to a
   consistent square or circle aspect ratio so five different authors' bios don't
   have five different photo shapes.
3. In the wide column, a `wp:heading` (level 3, since this sits below the post's
   H1/H2 structure) for the name, a `wp:paragraph` for the title, a `wp:paragraph`
   for the bio text, and a small `wp:social-links` or plain linked-text row for
   the social/site links.
4. Since each author's version of this block will be a separate synced pattern
   instance (or the same pattern with per-post overrides if using pattern
   overrides), make sure only the name, photo, bio text, and links are meant to
   change, the surrounding structure, spacing, and border should stay identical
   across all five so the site doesn't end up with five slightly different bio
   designs by accident.
5. Output the complete block markup once, using Elena's details as the filled-in
   example.
