/* ============================================================================
   KONYA DİŞ HEKİMİ — NAVY REDESIGN  ("Clinical Precision")
   ----------------------------------------------------------------------------
   Full visual redesign delivered as a modular, reversible theme layer, scoped
   entirely under  html[data-skin="navy"].  Nothing in style.css is removed;
   this layer overrides design tokens + restyles components so the structure,
   content, SEO, JS behaviour and responsive breakpoints stay 100% intact.

   Design language: deep navy + white + cool grays + one soft-blue accent.
   References: Apple / Stripe / Linear / Vercel restraint, healthcare trust.

   ROLLBACK: change data-skin="navy" back to "premium" (or remove it) in
   index.html + tools/gen_pages.py, re-run the generator. Done.

   STAGE 1 of the staged redesign: design system (tokens + type) + hero +
   global component baseline. Per-section bespoke layouts follow in later stages.
