- **Tag filter bar** appears above the grid whenever any download has tags assigned. Chips for "All" + each unique tag, centered under the heading.
- **Clicking a tag** filters the grid to only matching downloads. Clicking the active tag again (or "All") clears the filter.
- **Empty state** — if a tag has no results it shows a friendly message instead of a blank grid.
- The filter only shows when tags exist — so it's invisible today (your 3 current downloads have no tags) and appears automatically once you start tagging items in the admin.
To use it: go to Admin → Downloads → edit a download item → add tags like `Colossians`, `Worksheet`, `Devotional`. Those tags will show up as filter chips on the public page instantly after publishing.
