/* ================================================================
   SmallStack search — topbar omnibar styling.

   Shares the editorial-cinematic aesthetic of /smallstack/search/:
   italic serif typography, monospace labels, hairline rules. Compact
   enough to feel like a command palette but typographically
   confident.

   All values reference palette tokens so the omnibar renders
   correctly across every dark palette (django / blue / purple /
   orange / high-contrast).
