BitNumberField now supports theme tokens, public CSS variables, validation and loading states, cascading parameters, updated ARIA behavior, size variants, reorganized demonstrations, and expanded automated coverage.

BitNumberField contracts and propagation

Component contracts and parameter propagation src/BlazorUI/Bit.BlazorUI/Components/Inputs/NumberField/...	Added validation, loading, size, accessibility, and cascading-parameter support. Added BitNumberFieldParams to propagate unset parameters and invoke numeric setters.

Accessibility and state rendering src/BlazorUI/Bit.BlazorUI/Components/Inputs/NumberField/BitNumberField.razor, src/BlazorUI/Tests/.../NumberField/BitNumberFieldTests.cs	Moved ARIA attributes to the input, added hidden-input grouping, error and loading regions, persistent status announcements, and inert spin-button states.

Custom error templates are not politely announced, explicit labels can be ignored for hidden-input steppers, and copied demo code will not fully match the displayed examples. These are bounded issues that should be corrected before release.

In
`@src/BlazorUI/Bit.BlazorUI/Components/Inputs/NumberField/BitNumberField.razor`:
- Around line 75-76: Update the aria-labelledby expression on BitNumberField so
it is set in HideInput mode only when AriaLabel has no value and a label or
label template exists; preserve aria-label for explicit AriaLabel values.

In
`@src/BlazorUI/Bit.BlazorUI/Components/Inputs/NumberField/BitNumberField.razor.cs`:
- Around line 1247-1250: Update the LiveText property in BitNumberField so an
ErrorMessageTemplate-only error provides non-null announcement text for the
role="status" live region instead of returning ErrorMessage. Preserve the
existing ErrorMessage, loading, hidden-input, and null behavior, and extend
BitNumberFieldErrorMessageTemplateShouldRenderInPlaceOfTheMessage to assert the
live-region status content.

In
`@src/BlazorUI/Demo/Client/Bit.BlazorUI.Demo.Client.Core/Pages/Components/Inputs/NumberField/BitNumberFieldDemo.razor.samples.cs`:
- Around line 435-447: Synchronize the displayed samples with the live
configuration: add the Info accent to the cascading-parameters sample’s
BitNumberFieldParams entry, and update example25ScssCode to include the live
stylesheet rules for .custom-class *, .custom-input,
.custom-input-wrapper::after, .custom-focus .custom-input-wrapper::after, and
.validation-message.
