Why is sapphire not the main story?
Because the site is intentionally positioned around quartz precision fabrication first.
This zh-cn route keeps sapphire visible without weakening the site's quartz-first positioning.
Replace with sapphire parts or application imagery later.
Sapphire belongs on the site as a secondary material line, especially for optical and analytical contexts.
This route exists to support material-fit discussions while keeping quartz central.
This zh-cn sapphire page is a placeholder implementation aligned with the English route.
