Ship the full Resources demo content so the listing, its filters and its pager can be seen

Problem/Motivation

The Resources page is the site's field-updates section, and the design shows it as a filterable grid of cards running over several pages. The site template ships three blog posts, so on a fresh install the page renders a single short row: the pager never appears, the exposed filters have almost nothing to filter, and a site builder cannot see how the section behaves once it holds real content.

The three posts also carried no categories or tags, so the Type filter did not render at all and the card badges in the design had no data behind them.

Steps to reproduce

1. Install the Horizon Aid site template.
2. Open /resources: three cards, no pager, and no Type filter.

Proposed resolution

• Ship twenty-six blog posts as default content, written as field updates, reports and policy briefs, so the listing fills three pages at nine per page and the pager is visible and usable.
• Add the three categories the design shows as card badges: News, Report and Policy brief. This also makes the Type exposed filter render.
• Add the three themes the design lists beside the updates: Healthcare & Medicine, Sustenance & Growth and Universal Education.
• Add nine high-resolution images taken from the design's resource images, at the size the drimage crop needs, each with an editor-facing name and alt text.

This is default content only: no configuration changes, and the listing view is untouched.
