/* ============================================================
   STHERB — Nano Boost Landing (Redesign)
   Scoped to template-nano-boost-redesign.php

   Per explicit user decision 2026-07-10, this page keeps its OWN
   "nano + silver" base palette from the mockup (full base-token repaint,
   same pattern as Essential Care's sage+gold) rather than the Women's Care
   rose theme. Every custom property AND every component override below is
   scoped under `.sr-nb-scope` — a wrapper div around this page's own
   content only, placed between the shared header and footer in the
   template (NOT on <body> or `.stherb-redesign-home`, which the
   header/footer are also inside) so the repaint can't leak into the
   shared chrome (keeps the site's standard blue --accent there).
