SF-32 Cinematic Liquid Glass Leopard redesign for iOS and macOS

Scope

Evolve the native SonicFlow experience from the existing dark-card Leopard Look into the selected Cinematic Leopard Hero direction.

Deliverables

• iOS SwiftUI main screen uses a large mode-driven hero, stronger leopard wallpaper presence, and native Liquid Glass surfaces where available.
• macOS menu-bar popover mirrors the same hero/control hierarchy in a denser popover-appropriate layout.
• Shared native SwiftUI helpers keep glass/material treatment consistent and provide fallback materials for earlier OS versions.
• Existing audio/session behavior remains unchanged.

Acceptance

• Current mode becomes the visual hero and primary context for the session.
• Start/Pause is the dominant action; secondary controls stay compact and readable.
• Leopard imagery is visibly brand-forward but never sits directly under body text without a glass/material surface.
• iOS and macOS builds/tests pass with the local verification commands in the implementation PR.
