/* Safety net: every inline icon in this project relies on CSS for its size.
   Without this, any icon that is ever added without a matching class rule
   would fall back to the SVG spec's default replaced-element size
   (~300x150px), rendering as a huge filled shape. 1em keys it to the
   surrounding font-size instead — small and inert by default — and every
   real icon still gets its own explicit width/height from a more specific
   selector further down, which wins on specificity. */
