@carlmw this may be because it is behind the feature flag, but I've noticed the height of the nav bar in the header change while the 'Download' button loads in - just checking if this would carry through to live?

yes it will, it's not related to this PR though. I think it's down to the size of the download button increasing the nav bar height when it appears. It's a small fix.

For my part, happy to approve, factoring in the couple of things discussed in the pr.

@messmike sorry for the mixup, but subject category toggles have been added now

Couldn't find an example in Figma, but i've tried to make them as consistent as possible with the filters on the programme page.

@messmike pushed a little fix to correct this, it was bothering me a lot 😆
