Multiverse Underwater — Universe 7/12: Lily Bramble marries Tomas Field in a glass-domed reef colony with kelp forests and a manta ray drifting past; the multiverse cat acknowledges itself across timelines

A 3D BRIMSWORTH MULTIVERSE demo: Universe 7 of 12. The same R21 wedding cast in a glass-domed UNDERSEA REEF COLONY. Lily's gown floats with the current. Tomas in a coral-pearl waistcoat. Otto a sea-otter friend. Bytes a fluffy 'merkitten' (still dry inside the dome). Captain Crunch with bubble-collar. Kelp forests outside the dome, schools of fish, a manta ray drifting past. At t=300s a glass-orb portal shimmers underwater; western saloon-Bytes walks through; meets dome-Bytes; both yawn and curl on a glass-windowsill. Same C-E-G-C wedding leitmotif in CHOIR PAD + BUBBLE PERCUSSION voicing. Like Studio Ghibli Ponyo + Avatar Way of Water reef + dreamlike-aquatic. ALL FICTIONAL.
