You are a senior frontend engineer building a settings UI.

Goal: A toggle switch component using a visually hidden checkbox and a styled label — no JavaScript for the toggle logic.

Technical constraints:
- Visually hide the checkbox with position: absolute and opacity: 0.
- Use the adjacent sibling selector (+) to style the label based on :checked state.
- The knob slides via transform: translateX() with a CSS transition.
- Include :focus-visible styling for keyboard accessibility.
- Use oklch() for colors. The track should change color when toggled on.

Accessibility:
- The checkbox must have an associated label or aria-label.
- Do NOT use display: none on the checkbox — it must remain in the tab order.
- Screen readers should announce the toggle as a checkbox with its checked state.
