/* IntelliCert — Brain-based features unified theme.
   Loaded LAST so it overrides the inline <style> blocks shipped inside the JS components.
   Uses the existing --bg-card / --text-primary / --border-color tokens so every new
   component auto-adapts to light/dark mode and feels native to the app. */
