API

`Spinner`

Prop	型	既定値	説明
`as`	`ElementType`	`"div"`	as="span"などで、描画するルートタグを変更します。
`className`	`string`	—	クライアント側のスタイリング用に、クラス名をルート要素に転送します。
`align`	`"center" \| "fixed" \| "absolute"`	—	スピナーを通常フロー、ビューポートへの固定、絶対配置のいずれかで配置します。
`children`	`ReactNode`	—	ステータス領域のアクセシブルな名前とともに描画する可視の内容。
`value`	`number`	—	0〜100の固定パーセント値。アニメーションを静的な円弧に置き換え、ロールを progressbar に切り替えます。
`delay`	`number`	`0`	スピナーを表示するまでの待機時間（ミリ秒）。CSSで適用するためJavaScriptは不要です。
`label`	`string`	`"Loading"`	ステータス領域が読み上げるアクセシブルな名前。
`showLabel`	`boolean`	`false`	可視のラベルを`[data-part="label"]`パーツとして描画します。
`size`	`"small" \| "default" \| "large"`	`"default"`	CSSのみのスピナーの直径を制御します。
`render`	`ReactElement \| ((props, state) => ReactElement)`	—	動作とアクセシビリティの接続を維持したまま、描画する要素を置き換えます。
