/* Aardvark Decor homepage trailer ("The Reel") - Lane 1
   Presentation only. Consumes existing tokens plus the two approved literals
   (#120b05 deep brown ink, #fffaf2 warm cream). No new colors, no libraries.
   Every animation is gated behind motion-safe AND data-motion!=off, so the
   page is a complete, static editorial layout without JS or with motion off. */
