Making this a meta to work on each component in its own ticket.

Note that the code here has been merged into main.

Removing parent so I can close it.

Alan has take over the slot refactoring... yay!

But I'll do the YAMLs as he's finishing components.

WIP MR is here:

I'll merge the MR after getting the videos up.

Best to watch in this order:

• Case study testing
• Hero testing
• Cards and testimonial testing
• CTA testing

• Slider testing (part 1, screen share goes away at around 3:45)
• Slider testing (part 2)

This is done. See videos above.

Finetuning will happen in followup issues based on:
