Walkthrough

BitOverlay gains new positioning, styling, accessibility, scroll management, and programmatic control features. Its demo page and tests now cover the expanded API, visual states, click behavior, scroller selection, lifecycle cleanup, and accessible rendering.

Changes

BitOverlay improvements

Layer / File(s)	Summary
Overlay parameters and lifecycle `src/BlazorUI/Bit.BlazorUI/Components/Utilities/Overlay/BitOverlay.razor.cs`	Adds `AbsolutePosition`, `Center`, `DefaultIsOpen`, `ModeFull`, `ScrollerElement`, and `ZIndex`. Adds `Open()`, `Close()`, and `Toggle()`. Updates scroller resolution, scroll restoration, offsets, and disposal handling.
Accessibility and visual rendering `src/BlazorUI/Bit.BlazorUI/Components/Utilities/Overlay/BitOverlay.razor`, `src/BlazorUI/Bit.BlazorUI/Components/Utilities/Overlay/BitOverlay.scss`	Decorative overlays render `aria-hidden="true"`. Closed overlays use opacity and visibility transitions. New classes support centered content, full-mode dimming, and absolute positioning.
Behavior and rendering tests `src/BlazorUI/Tests/Bit.BlazorUI.Tests/Components/Utilities/Overlay/BitOverlayTests.cs`	Adds coverage for accessibility output, state precedence, clicks, scroll locking, disposal, imperative methods, offsets, positioning, and styling.
Overlay documentation and demos `src/BlazorUI/Demo/Client/Bit.BlazorUI.Demo.Client.Core/Models/ComponentCatalog.cs`, `src/BlazorUI/Demo/Client/Bit.BlazorUI.Demo.Client.Core/Pages/Components/Utilities/Overlay/*`, `src/BlazorUI/Demo/Client/Bit.BlazorUI.Demo.Client.Core/Shared/MainLayout.razor.NavItems.cs`	Expands parameter documentation and examples for overlay modes, events, scrolling, styling, programmatic control, and RTL content. Updates catalog and navigation metadata.

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

Merge Risk: ⚪ Minimal · up to b7b24

The overlay changes remain merge-ready after normal checks and review; no actionable merge-blocking risk remains. The demo text should still be corrected so app-shell users understand the actual scroller fallback order.

Poem

A rabbit taps the overlay bright
Centered softly, dimming the night
Scroll locks close, then springs away
Clicks count three, then end the play
New paths bloom in tested light
