/* VIDIUM Event Networks — landing page styles
   Built on tokens.css + components.css. Reach for tokens, not raw values.
   Default surface is Signal (dark); blocks use mode-aware tokens so the
   Control/Signal toggle keeps working. A few "always-dark" instrument
   blocks (hero stage, NOC dashboard) pin graphite like the live player. */
