   NURR v13 — panel design reset
   Purpose: one contained liquid-glass panel system, without leaking styles into
   module internals. Edit panel shell/spacing here; module-specific preview fixes
   are scoped by .mode-gradient / .mode-geometric / .mode-glass3d / .mode-nature /
   .mode-abstract only.
