The grid pattern was a 360° repeating conic gradient (visible across
the full upper 180° arc), while the needle only swings -45..+45.
That made the rest position at -45 sit *inside* the visible arc
rather than at the leftmost gridline — looked wrong.
Now:
- Grid lines start at the -45 angle (matches needle origin)
- Conic-gradient mask clips visibility to the 90° active wedge
- Leftmost gridline now coincides with the needle's rest rotation
→ looks like a real VU meter at zero (silence)
