Goal

Fade the lights in over a configurable window at the on-transition (sunset) and fade out at the off-transition (sunrise), instead of snapping to full/zero brightness.

Why it's valuable

A small change with an outsized polish payoff — a slow ramp at dusk reads as intentional and premium. It's a pure scheduler/push refinement with no schema impact.

Sketch

New settings: RAMP_ON_MINUTES / RAMP_OFF_MINUTES (0 = current snap behavior).
Scheduler interpolates global brightness across the window via short interval pushes, or uses WLED's transition/nightlight features where possible to offload the ramp to the device.
Respect the late-night dim target as the ramp ceiling after dimming.

Acceptance criteria

Configurable fade-in at on-time and fade-out at off-time
0 preserves the current instant behavior
Interacts correctly with late-night dimming
Tests for ramp endpoints/edge times

Proposed enhancement (brainstorm follow-up).
