/* ═══════════════════════════════════════════════════════════════
   TroubleShooting — Clon funcional del proyecto de referencia (Next.js)
   reconstruido NATIVAMENTE en CSS vanilla, SIN dependencia con la carpeta
   `Troubleshooting-Reference/` (solo se tomó como referencia visual).

   A diferencia de la versión anterior (chrome navy fijo), este clon adopta el
   LENGUAJE VISUAL del proyecto: shell igual al del "Agente IA" (sidebar estilo
   .sb + header estilo .hd) y TODO el color sale de tokens.css → respeta los
   temas dark/light. El navy de marca (--navy) solo se usa como ancla de chips
   de código (legible en ambos temas).

   Namespaces:
     · ts2-*  → shell (overlay, sidebar, header, contenido) y páginas del clon
                (dashboard, cuadrículas, hero de máquina, detalle de sistema…).
     · ts-*   → detalle de falla, candidatos y autoría. Se conservan estos
                nombres porque la API pública (window.TPTrouble) los inyecta
                también en el CHAT (fuera del overlay): deben verse bien en
                ambos contextos y temas.
