What changed
- Term Structure, IV Premium, and Expected Move now use one shared expiration overview.
- IV Premium highlights locally expensive or cheap expirations without plotting unavailable endpoints as zero.
- Surface places expiration dates on the horizontal axis and actual option strikes on the vertical axis.
- Mid, Call, and Put IV modes use a relative blue-to-red scale with exact strike, spot, and distance details on hover.
- Expected Move Cone compares current ATM-straddle ranges across selectable 30D, 90D, 180D, and All horizons.
