/* ============================================================================
   OME Panel — "Control Room / Signal" identity.
   Broadcast console: console-black surfaces, tally-amber action, signal-green
   live, on-air red. Tokens drive every shared component; retint here to reskin.

   Token scope (U1): color, type scale, radius, elevation shadow, and the
   padding/margin/gap spacing rhythm are fully tokenized below — no raw hex or
   ad-hoc size remains in a page rule for these five categories. A few classes
   of literal px are intentionally left as-is because they aren't "drift" in
   the sense above:
     - @media breakpoints: CSS custom properties cannot appear in a media
       feature without a build step (this project has none by design), and
       the breakpoint set itself is U3's job.
     - border-width: 1px (a universal CSS idiom, not a rhythm value).
     - one-off decorative details: glow blur-radii, vertical-align nudges,
       icon/thumbnail/logo pixel dimensions, transform/opacity/duration/
       z-index/letter-spacing values.
