✅ Looks great! Clean, minimal, and correct fix.

The use of trackedImports.length = 0 (mutating in place rather than reassigning to []) is the right approach here — it preserves the array reference used across closures in the plugin. Resetting in buildStart is the correct hook for this since it fires at the beginning of each build cycle in watch mode, before transform populates the array again.

The changeset is correctly marked as patch.

💡 Suggestion (non-blocking)

• plugins/css-colocate/index.ts:30–37: Since trackedImports.length = 0 and preprocessCssModules are both in buildStart, it's worth noting that if preprocessCssModules throws, the reset still happened — which is fine and actually desirable (stale imports from a failed prior build shouldn't carry over). No action needed, just confirming the ordering is intentional and correct.

Nice work! 🙌
