Summary

Remove the public spoiler toggle and the URL/stored-preference unlock path. Keep unreleased content hidden by default, and show the shared unreleased-content notice on locked chapter pages.

Changes

• Remove SpoilerToggle from ContentSettings.
• Make the public spoiler state always locked; ?Spoiler=allow and the local-storage preference no longer enable unreleased content.
• Remove the spoiler preference keys from the storage config.
• Remove the spoiler URL handling from the theme bootstrap script.
• Show the shared unreleased-content notice on unreleased story chapter pages.
• Update the notice copy in the five core locales.
• Rewrite the spoiler settings tests around the locked public state.
