## How to Play

Navigate the grid and fill or mark cells based on the numeric hints along
each row and column. The hints tell you how many consecutive filled cells
appear in that line, in order. Hints turn green when a row or column is
correctly satisfied.

- **Filled** cells count toward hint satisfaction.
- **Marked** cells are visual reminders that a cell should stay empty.
- The puzzle is solved when every row and column matches its hints.
