The site MUST provide a blog index page at `/blog` that lists WordPress posts as cards containing:

Each post card MUST be instrumented with Umami Track Events data attributes and MUST include at minimum:
- `data-umami-event`
- `data-umami-event-target_id`
- `data-umami-event-placement`

- `data-umami-event`
- `data-umami-event-target_id`
- `data-umami-event-placement`
