I’d keep it as quiet as a library at midnight, with soft, neutral colors and gentle ambient sounds that aren’t demanding. The layout would be minimal, a few personal spaces like a small reading nook and a soft floor mat for meditation. You could add a few personal touches—a favorite photograph, a small plant, or a scent diffuser—so the space feels like your own breathing room. The key is to limit notifications, use simple navigation, and let the mind drift instead of chase it.

I’d keep navigation almost invisible, just a soft, slow tap or a faint breath‑in, breath‑out cue. It should feel like the room itself is guiding you, not a menu or button. A gentle hand gesture that feels natural, like a wave to turn a page, would work best. It keeps the focus on the space rather than the tech.

I’d lean toward muted earth tones—soft greys, gentle taupes, maybe a hint of sage green. For sound, a low‑frequency hum that feels like distant wind, or a faint ripple of water. The key is subtle, not demanding, just enough to anchor the feeling of stillness.
