Slight typo - spurious ) after (max-min)

I think I see why you used a largeish triangle, a smaller one shows slight misalignment which I can't fix for all gauge sizes.

Happy to help but my skill level isn't up to the coding. I can opine on appearance though.

Some wild suggestions for widget settings, I have no idea if these could be made variable:  
Adjustable border-radius 0 to 50%  
Fasteners: rivets/slot head/square drive screws/none  
Background image (texture): Choice of a couple of SVG images/none  
Be able to show 360 degrees and hour/minute/second hands.  
Should pointer(s) be an SVG image?  
Various colour options.  
A "backlight" layer that can be turned on to draw attention to a particular gauge.

Here's square drive screws (only really visible on 6x6 gauge):

```auto
.g-rivet::before {
    content: '';
    position: absolute;
    left: 43%;
    top: 50%;
    width: calc(var(--container-size) * 8%);
    height: calc(var(--container-size) * 8%);
    box-shadow: inset 0px 1px 2px #222;
    transform: translate(-50%, -50%);
    border-radius: 0;
}

```

But really it's an amazing piece of design work already. Thanks hotNipi.
