/* ============================================================
   REFINED POLISH — single layer, modern-minimalist quality
   Replaces all prior polish iterations. Scoped, non-destructive,
   focused on type rendering, focus rings, and transition easing.
   No universal border overrides. No layered shadows. No heavy
   chrome. Inspired by Harvey / Linear / Vercel design vocabulary.
