Stroker order has wrong color and text shadow

[wrex]

I think maybe it's just the first unexpanded info section, but I noticed "Stroke Order" was ugly today:

I think we need to add something like:

.item-info-injector-accordion > button {
    color: var(--ED-text);
    text-shadow: none;
}

Oh! I forgot this was added by the Stroke Order user script.

It needs to go into that stylesheet.

Actually, scratch that. It affects any scripts that add an accordion section. The fix belongs in the main stylesheet.
