trigger()

void fl::TimeRamp::trigger ( u32 now )

overridevirtual

Call this when you want to (re)start the ramp cycle.

Smart re-trigger that preserves state when already active:

• If in plateau: extends the plateau time
• If falling: reverses back to plateau
• If rising: continues rising
• If inactive: starts new cycle

Implements fl::TimeAlpha.
