K1 materiality game

Each case is a recipe where K1, run on all 723 submissions after K0 with the newest rules, gives a different Title, Cook Time or Extras from L2 corrected. Every case page has the walkthrough's layout: Raw, L1, L2 corrected, K0 and K1 in the left side bar, K1's result next to L2 corrected with differences in bold, and Back, Next and a box to write in at the bottom. What you write saves when you click Back or Next, press Enter, or click out of the box. Start at case 1.
