Sequential Timeline
Order days as Monday→Sunday. Map constraints: 'earlier than', 'before', 'neither first nor last'.

Use inequalities to form partial orders and then linearize.
Verification:
- Priya's talk is earlier than Jatin's.
- Kaira's talk is neither first nor last.
- Nihal's talk is before Zoya's.
