/* ============================================================
   RenderAI — il BLOG col vestito della landing (novembre 2026)
   Un carattere solo (Inter), fondo blu-nero della landing, oro solo come accento.
   I tasti sono quelli di /tasti.css (.rt-oro / .rt-neutro), smussati a 10 px dove sono bassi.
   Testi a colori PIENI: niente trasparenze sulle scritte (regola del marchio).
   Prende il posto di assets/style.css (Bebas Neue + JetBrains Mono, luglio 2026).
