   The 28-px canvas had whitespace inside it, so the math-true sizes
   render the visible logo smaller than the original looked. Heights
   scaled 2× so the rendered logo matches the user's intended size:
   image viewBox h=55 → 30px; wordmark h=50 → 28px; tagline h=18 → 10px.
   Tagline subsequently bumped 10 → 12 px (effective font ~8px) for

   size, which read too small at body distances. */
