/* ==========================================================================
   SurgeLab v2: the October 2026 redesign.
   Square corners, 1px ink rules, hard offset shadows, Bebas Neue headlines.
   Pages move onto this file one at a time; pages not yet moved keep site.css.
   Section-specific layout lives inline in each page (it is one-off art
   direction). Everything shared across pages lives here.
