/* Vertical rhythm for page sections.
   Tightened 2026-09-04 at Matt's request: --section-y was clamp(56px,7vw,96px),
   which put 96px above and below every .pw-section, so 192px of empty band
   between any two stacked sections. Measured on Services (5 sections) that was
   4202px of page; at 64px it is 3818px, a 9% reduction, and 128px between
   sections still separates them clearly. Ample padding reads as wasted space on
   an industrial site. --section-y-lg is unchanged. */
