Replace multi-page portal with hash-routed SPA, DFTE shell placeholders, and
data-first JSON APIs. Remove legacy routes, root-template override path, and
HTML-derived info pipeline. Add bootstrap feature flags, in-DOM toast/dialog UX,
OTA via POST /u, and tests for shell, bootstrap, API JSON, and captive host rule.
Rewrite README as fork disclaimer and modernization overview.
Harden the root placeholder path, add direct render-isolation coverage, move simple status pages and /info onto request-scoped streamed templates, and switch /wifi to a streamed shell while keeping scan/form sections string-built for now.
Keep root template state request-scoped so dynamic placeholders stay consistent during chunked renders, add reserve() coverage for non-streamed pages, and add compile/test coverage for the new root render lifecycle.
