  Wayfinder - the signature element. Deliberately the one component that
  goes dark (Bone Ink chrome): everywhere else on the site is a light,
  paper-toned reading surface; this is styled like the radiology
  lightbox/viewer instrument it's modeled on, so the contrast reads as
  intentional - stepping into a diagnostic tool and back - rather than
  inconsistent. See the design-token sign-off's self-critique log.

  rendered far taller than one screen (reported: "too large... scrolling
  way too down"). max-height + width:auto lets the browser use the
  viewBox's intrinsic aspect ratio to shrink proportionally against
  whichever bound is tighter, the same way object-fit:contain works for
  an <img> - width:100% alone only ever looks at the horizontal bound.
  Harmless for the cranial tab (~0.77:1, landscape) since its natural
  height at max-width never gets close to this cap.
