Aligning the mockup more closely with the reference image:
- Knob body is now a pure charcoal/black radial gradient (no warm
brown tint). Top-left specular dim, top crescent gloss, outer dark
ring. Drop shadow underneath so the knob "sits on" the panel.
- Value readouts ("120.0", "2.50", ...) in cream/white, no inset
amber LCD frame. Amber is reserved for arcs / LEDs / bullet labels
exclusively.
- Panel palette pulled toward neutral dark (less brown saturation).
- Sidebar with the description bullets removed; layout is just the
hardware unit at full width.
