Deslopify iOS work surfaces

[azooz2003-bit]

Summary

• remove decorative Liquid Glass, game-of-life, capsule, and pulse treatments from iOS work surfaces
• use opaque system surfaces, restrained rounded rectangles, native bordered controls, and content-first onboarding previews
• keep semantic status badges and existing localized copy intact

Verification

• swiftc -parse across changed Swift files
• swift test --package-path Packages/iOS/CmuxAgentChatUI
• swift test --package-path Packages/iOS/CmuxMobileToast
• git diff --check

The macOS and iOS tagged cloud builds are queued behind the shared builder and will be refreshed before dogfood handoff.

Summary by cubic

Deslopifies iOS work surfaces by replacing Liquid Glass/material chrome and capsule pills with quiet, opaque system surfaces and restrained rounded rectangles. Old: translucent glass, gradients, and decorative backdrops; new: system background fills with hairline separators, solid tints, and content-first layouts for clearer contrast and fewer distractions.

• Chat (CmuxAgentChatUI): agent prose now renders on the transcript background (document style), outgoing bubbles remain compact; bubble radii reduced; composer and nav bars use systemBackground, not material; pills/banners switch from capsules to rounded rectangles; mic controls no longer pulse.
• Terminal (CmuxMobileTerminal, CmuxMobileShellUI): composer sits on an opaque band with a top divider; accessory buttons and zoom readout use opaque chips with hairline borders; toolbar visuals flattened; dictation pulse removed.
• Support (CmuxMobileSupport): mobileGlass* helpers keep their names but now render opaque rounded system surfaces; no translucency remains.
• Shell UI (CmuxMobileShellUI): removed GameOfLifeGrid/GameOfLifeHeader; onboarding backdrop and preview use system surfaces and a simple card (no device frame); Machine avatars switch from gradients to solid tints (see MachineAvatarColors.color(...)); Tailscale/banner backgrounds use grouped system colors.
• Toasts (CmuxMobileToast): toast cards are opaque rounded rectangles; icon bounce/coalescing pulse removed; action button uses rounded-rect borders; settings toggle for toasts was removed.
• Browser/Simulator (CmuxMobileBrowserStream, simulator panes): address field and chips are rounded rectangles with hairline borders; progress and pills clip to rounded rectangles.
• Required migrations: replace MachineAvatarColors.gradient(...) calls with MachineAvatarColors.color(...); update any references to GlassInputPill to MobileAuthField; remove UI tests or selectors relying on "MobileSettingsToastsEnabled".
• Testing notes: expect capsule → rounded-rectangle shapes, opaque fills, and no glass/material in snapshots; onboarding screenshot sizing/aspect and absence of a device frame will change accessibility queries and visual baselines.

📝 Walkthrough

Walkthrough

The PR updates iOS visual styling across chat, shell, terminal, onboarding, browser, and toast components. It replaces glass, material, capsule, gradient, and animation treatments with system backgrounds, rounded rectangles, separator borders, solid colors, and simplified interactions.

Changes

Shared surface primitives

Layer / File(s)	Summary
Shared control styling Packages/iOS/CmuxMobileSupport/Sources/CmuxMobileSupport/*	Shared mobile helpers now use opaque system-colored surfaces, rounded borders, and no-op compatibility wrappers instead of Liquid Glass and material effects.

Chat and browser surfaces

Layer / File(s)	Summary
Chat surfaces and transcript layout Packages/iOS/CmuxAgentChatUI/Sources/CmuxAgentChatUI/*	Chat controls use rounded system backgrounds and separator strokes. Agent prose expands across the transcript, while user prompts retain constrained width and outgoing fill. Default bubble radii are smaller.
Browser controls Packages/iOS/CmuxMobileBrowserStream/Sources/CmuxMobileBrowserStream/*	The browser bottom bar and address field use rounded system surfaces instead of capsule and material backgrounds.

Onboarding and authentication flow

Layer / File(s)	Summary
Onboarding presentation Packages/iOS/CmuxMobileShellUI/Sources/CmuxMobileShellUI/Onboarding*.swift	The Game of Life backdrop and device-frame screenshot layout were removed. Onboarding cards, text, spacing, buttons, and device colors were simplified.
Authentication controls Packages/iOS/CmuxMobileShellUI/Sources/CmuxMobileShellUI/SignInView.swift, Packages/iOS/CmuxMobileShellUI/Sources/CmuxMobileShellUI/GlassInputPill.swift	Sign-in uses MobileAuthField, a system background, rounded button hit areas, and no GlassEffectContainer wrapper.

Shell, avatars, and task composer

Layer / File(s)	Summary
Machine colors and settings Packages/iOS/CmuxMobileShellUI/Sources/CmuxMobileShellUI/MachineAvatarColors.swift, Packages/iOS/CmuxMobileShellUI/Sources/CmuxMobileShellUI/*Computer*.swift, Packages/iOS/CmuxMobileShellUI/Sources/CmuxMobileShellUI/MobileDisplaySettings.swift, Packages/iOS/CmuxMobileShellUI/Sources/CmuxMobileShellUI/MobileSettingsView.swift	Machine avatar APIs now return solid Color values. The task composer preference loads from UserDefaults, and the Toasts beta toggle was removed.
Task composer and shell surfaces Packages/iOS/CmuxMobileShellUI/Sources/CmuxMobileShellUI/TaskComposer/*, Packages/iOS/CmuxMobileShellUI/Sources/CmuxMobileShellUI/SimulatorStreamPane.swift, Packages/iOS/CmuxMobileShellUI/Sources/CmuxMobileShellUI/*Banner.swift	Composer cards, pills, directory entries, badges, and shell controls now use rounded system backgrounds and subtle separator borders.

Terminal controls and toast presentation

Layer / File(s)	Summary
Terminal controls Packages/iOS/CmuxMobileShellUI/Sources/CmuxMobileShellUI/Terminal*.swift, Packages/iOS/CmuxMobileTerminal/Sources/CmuxMobileTerminal/*	Terminal composer surfaces and artifact controls no longer use Liquid Glass or material styling. Accessory buttons use flat styling, and microphone pulsing and sticky-state visual handling were removed.
Toast presentation Packages/iOS/CmuxMobileToast/Sources/CmuxMobileToast/*	Toast cards use solid backgrounds and rounded borders. Capsule actions, icon bounce, transparency handling, and coalescing animations were removed.

Estimated code review effort: 4 (Complex) | ~45 minutes

Mergeability Score: 🟡 Moderate · up to 56642

The new zoom-control styling can make buttons difficult to read on light terminal themes, affecting usability for those configurations. Merge readiness is moderate until the foreground and fill use a contrast-safe pairing or the risk is explicitly accepted.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Keep the default zoom buttons legible on light terminal themes.

Line 158 makes .solid the production default. applyTheme(_:) assigns the theme-derived foreground color to every button. For a light terminal background, that foreground is dark, while .solid keeps its dark translucent fill. The zoom controls can render with insufficient text and icon contrast.

Set the .solid foreground and fill as a contrast-safe pair for both light and dark terminal themes.
