1. Problem 1 - Y-coordinate based row calculation:
- Use Math.round(yCenter / cellHeight) instead of sequential filling
- Each character placed at correct row based on actual position
2. Problem 2 - Empty column detection:
- Implement detectEmptyColumns() method
- Calculate standard column gap and detect large gaps
- Map physical columns to grid columns accounting for empty columns
3. Problem 3 - Multi-column alignment baseline:
- Add findTopMostY() helper method
- Find reference baseline across all columns
- (Currently simplified, can be optimized later)
4. Fix double-line small character pairing:
- Use line_id sequence instead of x-coordinate splitting
- First line_id = right column, second = left column
- Pair by index after sorting by y-coordinate
