Slots and states that real apps kept building by hand, for MAUI and Avalonia, with demo sections on both platforms.

Components

• data-table: DataTableColumn.Cell draws any view in a cell (a badge, a link, a formatted amount). Filter and sort still use Property / Value. Set it before ItemsSource, or call Refresh().
• button: Size="Inline" (h-auto p-0) for a Link button in a line of text or at a card's edge.
• sheet: SheetHeader, SheetTitle, SheetDescription and SheetFooter, as on the web. They are new CLI targets, installed with sheet.
• card: CardHeader.Action at the top right (shadcn's CardAction). Views inside the header sit on the title's line (badges, a count) and wrap under it when there's no room.
• stat-card:
  • ValueTone (Default, Success, Warning, Destructive) tints the value.
  • The value row wraps, so the change pill drops under a long value instead of being cut off.
  • IsLoading shows skeletons in place of the value, so stat-card now depends on skeleton.
  • Size="Sm" fits six tiles to a row.
• input, input-group: Variant="Password" masks the text and adds an eye button that shows it. The button keeps the field focused and is named "Show password" / "Hide password" for screen readers. IsPassword still masks without the button. InputVariant lives in Input, so input-group now depends on input.
• icon: Receipt, ListChecks, CalendarClock, KeyRound (114 icons).

Fix

• MAUI page layer: the overlay layer is now set up as a page joins the app, before its views load. On a Shell route switch, the page's views were unloaded and loaded again, so a view that cancels its work on Unloaded lost its first load. On Windows, GoToAsync("//route") went from Loaded 2 / Unloaded 1 to 1 / 0. PageAppearing remains the fallback for content set later.

Docs

• Each component's section in COMPONENTS.md, plus the roadmap.
• Theme tokens on spans and runs (.Token(Span.TextColorProperty, …) already worked; now documented and shown in the demo).
• When the page layer wraps a page's content.

Checked

• Solution builds with 0 warnings and 0 errors (all four MAUI targets and the browser preview).
• Tests: 1740 core and 190 headless Avalonia, all passing. New ones: headless tests for each feature, and registry tests for the sheet parts and the new dependencies.
• Format clean on the changed files and the CLI project.
• Fresh apps outside the repo: Avalonia (add input-group stat-card sheet card data-table, and input-group on its own) and MAUI (add sheet stat-card card input input-group data-table button icon) build 0/0.
• Both demos driven in light and dark: password reveal, card header, stat cards, badge cells and sorting, sheet parts, span and run colours following the theme.
• Not run on Android or iOS: the page-layer change is built for them, not run.
