The mask + repeating-conic-gradient combo was rendering the visible arc shifted to the right (mask appeared centred on 12-3 o'clock instead of 10:30-1:30). Cause unclear — likely a browser quirk around `from -45deg` interaction between the two conic-gradients. Replaced with a single non-repeating conic-gradient using `from 315deg` (the positive equivalent of -45deg). Lines are drawn explicitly at every 9° from 0° to 90° in the gradient (-45° to +45° in standard orientation) — 11 lines total, with the centre line (at 0°) slightly brighter so it reads as the meter's "0 VU" mark. Outside the 90° active wedge the gradient is transparent, so no mask is needed. Result: the leftmost gridline now sits exactly where the needle rests at -45°, like a real VU meter at silence.
