fix(tv): transparent section ground behind the set

The TV section painted an opaque #060608 behind the chassis. That was
invisible while /newhome was pinned dark, but now the route follows the
theme it read as a stray black rectangle around the set on a light page.

The set is a physical object and carries its own dark chassis, so the
section only needs to sit on the page ground. The warm radial glow stays
— it is a halo around the object and composites over either ground.

The "ON AIR · GNARS TV" label is the only text outside the chassis, so it
is the only thing that sits on that ground. At the chassis gold it was
79% luminance on white; it takes a darker amber in light mode and keeps
the gold in dark.
