In the genesis-a2z theme the following PHP templates are used for the oik-plugins CPT.

Single page - single-oik-plugins.php
Archive page - archive.php

Requirement

Create FSE templates for both of these.

• single-oik-plugins.html
• archive-oik-plugins.html

Single page template parts

• Header
• Breadcrumbs
• Content

• Information
• Download
• Search
• Page footer
• footer

In the screen captures Content and Page footer are only partially shown. Footer is not shown at all.

Archive page

• Header
• Letters selection
• Breadcrumbs
• Category description. Is this really necessary for the Letters category?
• 3 column display of block title with link and featured image
• Search
• Page footer
• footer

Note: The 3 column display is different from that already delivered in archive.html, which uses category-query.html.
Looks like archive.html should use a different template part to implement the 3 column main query.
