   COCKPIT TOOLS — search palette, digit-jump toast, blackout screen, and
   speaker-note tier/plan chips. Shared by index.html and presenter.html.
   Chrome only: styled with the --ch-* tokens (app.css), never template tokens,
   so everything here is template-independent.
   z-order (app.css): toolbar 900 · overview 940 · modal 950 · gate 970 · toast 990.
