/* ===================== APS DARK THEME OVERRIDE (2026-05-30) =====================
   Aligns every shared-CSS page to the dark navy/cyan landing. Recolors through the
   existing tokens, switches type to the landing stack, and defines the canonical
   top nav and footer. Scoped so page-body components are untouched. Reversible:
   delete from this banner to end of file and remove the @import at the top. */
