1107 * 1. Site-wide settings are always stored with context_id 0, but the
1108 * frontend maps a homepage request to the `site` context while still
1109 * passing the queried object ID (non-zero on a static front page). That
1110 * looked up `site`/<page ID>, matched no row and silently fell back to

1112 * on a static front page. Normalize the ID away for `site`.
1113 * 2. `default_og_image` / `default_twitter_image` only exist in the site
1114 * context, so post/page and archive contexts had nothing to fall back to
1115 * when a post had no featured image — og:image dropped to the site logo
