## Play

- Browser: open `/` — pick a cell, then a digit. Givens are fixed; conflicts are rejected.
- JSON API (same engine): POST /api/games/sudoku {seed?} -> gameId;
  POST /api/games/sudoku/:id/set {cell:0-80, value:1-9|0}; GET /api/games/sudoku/:id.
- Cells are row-major 0-80; value 0 clears. Puzzles come from a built-in bank (unique solutions).

All games accept an optional `seed` (uint32) on create for deterministic practice replays.

Solo tables are practice play. Live-Vibes head-to-head activates per game only after the portfolio settlement gates pass.
