Constants

kBoardGridSize → const int: Width/height of the board grid, in cells.
kCenterCell → const List<int>: The single center cell every piece is ultimately heading toward.
kHomeBaseOrigins → const List<List<int>>: Top-left [row, col] origin of each player's 6x6 home base quadrant, in the same player-index order as kStartIndices.
kHomeStretchCells → const List<List<List<int>>>: Each player's 5-cell colored home stretch, ordered from its entrance (reached right after the 51st shared-path cell) to the cell adjacent to the center. Indexed by player (0-3), in the same order as kStartIndices.
kHomeYardSlots → const List<List<int>>: Local [row, col] offsets (within a 6x6 home base) where a player's 4 waiting pieces sit before entering the board.
kPathCells → const List<List<int>>: The 52 cells of the shared outer path, listed in clockwise travel order as [row, col] pairs. Index 0 is player 0's start cell; index 13 is player 1's; 26 is player 2's; 39 is player 3's (see kStartIndices).
kSafeIndices → const Set<int>: Indices into kPathCells that are designated "star"/safe cells. A piece sitting on one of these cells (including any player's start cell) can never be captured.
kStartIndices → const List<int>: Index into kPathCells where each of the 4 players enters the board.

globalCellOf(int playerIndex, int trackPosition) → int: Resolves a piece's relative track position (must be in 0..50, i.e. on the shared path — see LudoPiece.isOnSharedPath) for playerIndex to an absolute index into kPathCells.
gridCellFor(int playerIndex, int trackPosition) → List<int>?: Resolves any non-home track position to a [row, col] grid cell, for rendering.
isSafeCellIndex(int globalIndex) → bool: Whether the given absolute index into kPathCells is a safe cell.
