   ISSUE #6 — LAPTOP VIEWPORT FRAMING
   Common laptop heights received the large-desktop vertical rhythm,
   which pushed section headings low and left a tall empty band under
   the sticky nav — so after an anchor jump the heading sat too high
   with content below the fold. Tighten vertical spacing at laptop
   heights ONLY. Large desktops (taller viewports) and the mobile
   stack (≤880px wide) are untouched; container width, gutters, grids,
   and text alignment are all preserved.
