In this episode

* 00:00:43 Revert some of last week's changes to harvest later
* 00:01:32 We have a new story!
* 00:02:44 Review our current rendering code

* 00:13:30 Now switch to the new rendering...
* 00:14:13 ... and our approval tests will tell us how well we are doing with a nice diff
* 00:15:57 When we are close enough we can approve the new output
* 00:16:39 Now how about rendering just the table?
* 00:21:46 Unit tests pass - but the browser tests fail!
* 00:22:41 We can fix reshape output before approval tests
