/* Two SVG-specific gotchas, both verified in a browser rather than assumed:
   1. `transform: rotate(180deg)` is silently dropped on an <svg> element — the
      property is treated as the SVG presentation attribute, whose grammar
      rejects the deg unit. The standalone `rotate` property is unambiguous.
   2. Transitioning `rotate` on an <svg> parks the value at 0deg, so the icon
      never flips. Untransitioned, it flips correctly. The flip is instant by
      necessity, which also means there is no reduced-motion case to handle. */
