For poor CLS, check fonts only when the route actually loads external font CSS or swaps text after render.
Inspect layouts and global styles for external font links, CSS imports, custom font-face rules, late-loading font classes, and whether next/font is already used.
Do not migrate fonts when CLS is caused by images, ads, embeds, or injected UI. Do not suggest next/font for unsupported Next.js versions.
Name the CLS value, font-loading mechanism, and the exact layout or stylesheet line to change.
