   Synxum — Owner console · neutral dark theme
   ----------------------------------------------------------------------------
   Brand-NEUTRAL by mandate: placeholder name "Synxum" only, and NO
   operator-product names, logos, or colors anywhere. The look is a quiet
   "control-plane instrument": cool graphite surfaces, hairline borders, one
   restrained steel accent, neutral light primary action, semantic status hues,
   and a monospace system-readout identity (the live `// endpoint` tags).
   System font stacks only — no external font fetch.
