/* ============================================================
   vgwalter.com — "working paper" treatment

   Governing idea: the page presents itself as evidence rather than
   as marketing. Title block, abstract, numbered sections, specimen
   tables, margin glosses.

   Layout rhythm — the point is that width varies by section:
     §1  narrow measure + margin gloss   (reading)
     §2  two tracks: narrative | findings (working)
     §3  full-width registers + tables    (reference)
     §4  short, two tracks                (closing)

   Rules and tint carry structure. No cards, no shadows, no radius.
