Refresh the lobby and Start Call screens with the design system tokens - #1821
Merged
Conversation
The demo app and, later, the shared core-ui module (AND-1482) read the spacing, radius, size and typography primitives across a module boundary, so the object and its members become public API with explicit types.
The camera-off avatar uses the 80dp size token and the preview clip uses the large radius token. The controls keep their start alignment and the responsive tile heights stay as they are because no token matches them.
Dimensions and colors move to StreamTokens and the VideoTheme colors and typography, the material close button becomes a StreamIconButton, and the material icons that have a design system equivalent use it. The lobby header takes the same padding, avatar size and spacing as the Start Call header. Layout, strings, navigation and test tags are otherwise unchanged.
The nav host already applies the system bar padding; the activity only needed to opt in.
VideoPermissionsState learns whether the camera and microphone permissions were denied after a request. The default lobby controls request the permission again when the user taps the matching toggle, instead of leaving the system settings as the only way back. The toggle is still forwarded so the device turns on once the permission is granted.
The qr-code-fill icon joined the video icon set in design-system-tokens after the initial import, so it is added here and replaces the material QR scanner icon on the Scan QR Code buttons.

The lobby handler asked for the permission on every toggle, including the one that turns the device off, and the demo lobby bypassed it with its own action handler. A dismissed permission dialog reports an empty result, so the denied flag is now set on every completed request instead of per permission. The handler is remembered so the controls do not recompose on every device state change.
The token source spells the small end of each scale with repeated letters (xxs, xxxs) and the large end with a number (2xl, 3xl). The chat SDK already normalizes the small end to 2xs and 3xs, so the shared module planned in AND-1482 needs no rename on that side.

Goal
Closes AND-1513
Apply the design tokens and the base components to the lobby and the demo Start Call screen while keeping the current layout and functionality. This is the scoped version of #1816, following the agreement that the design refresh is not a redesign: tokens, base components and like-for-like icon swaps, no new layout decisions.
Implementation
StreamTokensbecomes public with explicit types on its members. The demo reads it, and the core-ui extraction (AND-1482) makes it public across a module boundary anyway.CallLobbyuses the 80dp size token for the camera-off avatar and the large radius token for the preview clip. The controls keep their start alignment and the responsive tile heights stay, no token matches them.StreamIconButton, and use the design system icons where an equivalent exists. The lobby header takes the same padding, avatar size and spacing as the Start Call header. Strings, navigation and test tags are unchanged.qr-code-fillicon joins the SDK icon set. It was added to design-system-tokens after the initial import and replaces the material QR scanner icon.VideoPermissionsStategainsisCameraPermissionDeniedandisMicrophonePermissionDenied(default false). Tapping a lobby toggle whose permission was denied requests it again instead of leaving the system settings as the only way back. The error badge from Redesign the lobby and the demo Start Call screen #1816 is not included.buildDefaultLobbyControlActions, and the non-Stream built-in demo user is replaced.Left out on purpose: the participant label styling, indicator sizes and large-avatar initials style are shared components and belong to the in-call tickets.
🎨 UI Changes
Lobby, camera off, before and after:
Testing
Manual: open the demo Start Call screen and the lobby in light and dark mode. The two headers line up: same top margin, avatar size and gap to the name, close and settings buttons flush with the 16dp margin. Deny the camera permission, then tap the camera toggle in the lobby: the system permission dialog shows again.
Ran locally:
spotlessCheck,compileDebugKotlin,:demo-app:compileProductionDebugKotlin,apiDumpfollowed byapiCheck,recordPaparazziDebugand thenverifyPaparazziDebug. The only golden change is the camera-offCallLobbyTestsnapshot, from the smaller avatar. The fourLobbyControlsCallActionHandlerTestcases pass.
