+## Docusaurus v4 Readiness
+
+Docusaurus 3.10 is the last v3 line and includes opt-in behavior that prepares sites for v4. Keep these as separate, deliberate follow-up tasks:
+
+- `future.v4.siteStorageNamespacing`: test `storage: { type: 'localStorage', namespace: true }` in a browser before enabling it, because it changes localStorage keys used by color mode and language tabs.
+- `future.v4.fasterByDefault`: do not enable this in the regular upgrade path yet. `future.faster` currently requires an additional v4 future flag in this project, so test it in a dedicated v4-prep branch.
+- `future.v4.mdx1CompatDisabledByDefault`: keep `markdown.mdx1Compat` enabled until docs are audited for strict MDX syntax.
