I'm trying to center vertically and horizontally a text inside an arc path but after add startOffset="50%", it turned upside down.
text a {
margin: 0;
font-size: 42px;
text-align: center;
font-family: sans-serif;
fill: #FF9800;
}
<svg viewBox="0 0 1277 224">
<path id="curve" d="M640 224c347.406 0 640-142 640-142V0S995 142.5 640 142.5 0 0 0 0v82s292.595 142 640 142Z"></path>
<text text-anchor="middle">
<textPath xlink:href="#curve" startOffset="50%">
<a xlink:href="#item-1">Item 1</a>
<a xlink:href="#item-2">Item 2</a>
<a xlink:href="#item-3">Item 3</a>
<a xlink:href="#item-4">Item 4</a>
</textPath>
</text>
</svg>
Update
I fixed the orientation issue but now I need to center vertically the text inside the arc.

Fixed!
I wrapped all the <a> tags with <tspan dy="25%">.
