   PADDOCK GARAGE: FLOATING GLASS SYSTEM
   Ported from the ACC glass spec: three depth-graded elevations
   (e0 recedes, e1 rests, e2 commands), dual inner bevels, film
   grain, one command surface per view. Adapted to the Paddock
   palette: ignition orange is the command ring.
   Loads after each page's inline styles; the cascade does the
   restyle so page copy is never touched.
