Gitea scrollbar in Safari is ugly

Can reproduce, but only in light theme. Wonder where that green is coming from, it also appears on the off-screen background when scrolling the page up with rubber-band scrolling.

It comes from HTML theme-color which Safari apparently now uses to color out-of-viewport content like scrollbar or overscroll area.

We could automatically to set theme-color via JS to match the current theme's --color-body so browser chrome on IOS and overflow match the body color, but that also means the color no longer be controlled via HTML, and I wonder if we should just remove the THEME_COLOR_META_TAG setting we have.
