   Implements the "VivaLogs Design System" handoff (claude.ai/design): a single light theme derived
   from the vision web template (slate #2D3748 header + sidebar, gray-50 body, 10px card radius), a
   violet VivaLogs accent distinct from the log-level colours, Inter typography and monospace for
   timestamps and messages. Suite-level chrome (VivaHeader, toasts, language switcher) keeps coming
   from the shared Vivaticket.Hub.Components RCL; everything VivaLogs owns is styled here.
