themeDoctor(theme) names the lighter mechanism for what a theme's CSS does
(radius, bevel, hiding, literal colors, fonts), its performance costs (:has,
universal selectors, blur, size) and accessibility costs (outline removed,
unguarded motion, small post text, moved navigation), plus contrast fixes.
Theme import adds the count and the first hint to its message. Tested.
