   RLabs Demo — three acts: (1) a Telegram phone mockup showing the request,
   (2) a terminal mockup showing the OpenClaw agent building + deploying on
   the VPS, (3) the shipped result — a canvas flock of birds on real flight
   curves, a CSS-built photographer (Ryan) who chases them and keeps missing,
   synthesized camera-click/whoosh SFX via Web Audio, and a spoken sign-off
   via SpeechSynthesis at the very end. Same engine family as Theresa's
   Sleep Study, reskinned as daytime sky.
