Key	Action
`←→`	Moves the focus to the previous or next year, wrapping to the neighbouring row. In RTL the arrows are mirrored: ← moves to the next year.
`↑↓`	Moves the focus to the year above or below in the same column.
`HomeEnd`	Moves the focus to the first or last year of the row.
`Page UpPage DownCtrl + HomeCtrl + End`	In a `YearPickerLayout` page: Page Up and Page Down move the focus to the first or last row in the same column; Ctrl + Home and Ctrl + End to the first or last year.
`EnterSpace`	Selects the focused year.

Every row is checked in a real browser: Playwright presses the key in Chromium and checks where the focus and the active item land.

Without defaultActive, the tab stop is the visible year, which is always on the page in view
Focus should remain visible as the year grid pages across larger ranges.

Large year ranges are easier to understand when the visible decade/range is announced clearly in nearby text or picker labels.
