V67 RESTORE OPPOSITE SIDE PETAL + LENGTHEN END PETALS

Base
- Starts from V66.

Changes
- Restores the opposite same-sign side petal.
- Makes that restored opposite-side petal about 1.5x longer than the existing side leaf (length-wise).
- Keeps the original side leaf outward-axis reduction at 0.5x.
- Keeps the strike-parallel visible full axis of the original side leaf near 1.4x the fault strike length.
- Keeps the end-petal outward offset at 3.5x.
- Also lengthens the end petals in the strike-parallel direction, because the previous version did not yet visibly reflect the requested increase there.

Other preserved settings
- Coast fix from V64 preserved.
