The Sudoku Grid Is ALL Fog??!

*** TODAY'S PUZZLE ***
We celebrate Missing A Few Cards' birthday today but trying another of their collaborations with Full Deck called I'll Cry If I Want To. And this puzzle might actually make you cry - it's a 'fog of war' sudoku with no cells revealed at all. Mark tested it and said it was VERY hard. Simon attempts it in a video and can confirm this assessment... but it's also as clever as you'd expect from two eminent math professors!

Play the puzzle at the link below:

Rules:
Normal sudoku rules apply. Along modular lines, every set of three contiguous digits has three different remainders when divided by 3. Numbers outside the grid give the sum of the first X digits (the "X-Sum") along that row or column, where X is the first digit seen from the direction of the clue. In addition to any modular lines revealed as the fog lifts, every X-sum forms a hidden straight modular line at least X cells long starting from the cell closest to the clue. Digits separated by a black dot are in a 1:2 ratio. ALL blacks dots are given. As correct digits are placed, fog will lift, potentially revealing more clues.
