Clarify Framey progress text placement

 | `PanelSection`, rows, buttons, toggles, dropdowns | Local touch-sized controls; disabled controls stay inert during a backend call | Local browser and host unit test |
 | `TextField`, `SliderField`, grouped `Dropdown` options | Native text, range and select controls in the panel; disabled state, numeric slider callback and basic input types | Host unit test; worn VR use unverified |
 | Scrollable panel content | Visible Scroll plugin up/down buttons move the last region reached by a trusted pointer, or the document if that region disappears. Hold either button to repeat; keyboard activation still moves one step. Plugins may use ordinary CSS overflow containers. | Parent/iframe message tests and a real Frame synthetic OpenVR pointer hold; physical controller scroll and hold remain unverified |
-| `Tabs`, `SidebarNavigation`, spinners, dialog/menu wrappers, progress bars | Local tab navigation and ordinary HTML controls; no Steam navigation or controller focus tree | Host tests and catalog frontend smoke checks in local Chromium |
+| `Tabs`, `SidebarNavigation`, spinners, dialog/menu wrappers | Local tab navigation and ordinary HTML controls; no Steam navigation or controller focus tree | Host tests and catalog frontend smoke checks in local Chromium |
+| `ProgressBar`, `ProgressBarItem`, `ProgressBarWithInfo` | Native progress control; `indeterminate` omits its value so it animates as unfinished, and `sOperationText` appears with the bar. Estimated completion time is not shown. | Host contract tests; official plugin progress behavior in worn VR remains unverified. |
 | `SteamUIStore` / `DFL.Router.RunningApps`, `MainRunningApp` | Bounded detached Steam CEF reads while the panel is open; refresh about every two seconds; no MobX observation. Failed reads clear stale context. | Locked real Frame empty-list reads; nonempty local Chromium fixtures. Real running-game selection unverified. |
 | `GameSessions.RegisterForAppLifetimeNotifications` | Actual Steam callbacks, bounded queue and disposable `.unregister()` handle; no events inferred from snapshot changes; lease cleanup after lost panels | Real Frame registration/poll/close; launch/exit, retry, expiry and duplicate tests use explicit fixtures. Real game transitions unverified. |
 | Other `SteamClient` subscriptions | Explicit inert registration methods return disposable handles; no fabricated power/input/game-action events. Mutating Steam/power methods are unavailable. | Host contract tests; safe fallbacks only |
