/* PracticeGraph — practicegraph.dev
   Design language v2: the page is typeset like the instrument's own printed
   reading — serif-led document, margin annotations, numbered exhibits, mono
   figures. Deliberately print-like: paper identity, near-zero motion.
   Custom property names are load-bearing (field-guide page scopes reference
   them) — do not rename. */
