The first cut was a flat stack of buttons. Reworked the chrome to match the windows-reactor gallery's look: - Mica backdrop on the window. - A centred, scrollable, max-width column (`page()` helper) instead of full-width sprawl. - Card surfaces (`border` + `ThemeRef::CardBackground`/`CardStroke`, rounded, padded) grouping content, with all-caps section labels. - Host rows are clickable cards: name (semibold) + address + a PIN/Open/Paired badge + chevron, laid out with a grid so the badge/chevron sit right; tap to connect. - Header row with title + Settings button; a ProgressRing while searching / connecting; settings as grouped "Stream" / "Audio" cards; the pairing screen is a centred card. Pure styling/layout — no logic change. Build + clippy + fmt green on x86_64-pc-windows-msvc. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
