/* The info/download toolbar buttons' icon SVGs are plain injected HTML, not
   PhotoSwipe's own built-in icon format -- they never get its ".pswp__icn"
   class (position/size) or its icon-color variable. Without this, the icon
   sits unstyled in each button's normal box flow and its `stroke="currentColor"`
   inherits whatever ambient text color the surrounding element/browser
   happens to use -- invisible-ish button text color in some browsers for the
   <button> info button, and the default link blue for the <a> download
   button (also shifted, since it isn't centered like PhotoSwipe's own
   icons). Fixed with an explicit, always-white color and the same
   position/size PhotoSwipe's built-in icons use. */
