fix: rewrite polar smile with correct closed-lens geometry

2026-05-21T21:49:56Z

- Piecewise angleFor: puts go CCW (ATM→bottom), calls go CW (ATM→bottom) so both wings meet at the same bottom point and the path closes with Z - Dynamic ivToR computed from actual IV range across all expiries (inner floor 60px, outer wall 240px) instead of hardcoded percentages - IV rings: 5 evenly-spaced steps between real ivLo/ivHi - Curve fill: rgba(194,170,122,0.12) matching design reference - Non-selected curves: index-based styles (solid fg-1, then dashed fg-2/3/4) - Eye price at font-size 30, label lowercase 'call · fair' - Dashed marker-line spoke from center to selected-K dot - Clicking a curve switches the selected expiry via onPickT - Strike ticks use round multiples of a price-adaptive step - Fix IvHeatmap xlabs duplicate key error (key by index, not rounded K) Co-Authored-By: Claude Sonnet 4.6
