   Tab Types — Native vs Cartridge (CN SOP-APP-001)
   
   Native Console tabs = OUTLINED (subtle, these are "home" tabs)
   Cartridge tabs (Console loaded as Cartridge) = FILLED (highlighted, external)
   
   This ensures Cartridges stand out as loaded external content.
   This law is enforced across all Consoles in the Contribution Network.
