Compile CSS-like selectors to TP structured ASTs and make TP the sole final matcher while Ebox retains logical tree adaptation and candidate indexes. Separate logical selector types from raw runtime type counts so internal flex adapters still drive bounded scroll scheduling without leaking into selector semantics.\n\nVerified: make check EMACS=/Applications/Emacs.app/Contents/MacOS/Emacs
Split the verified renderer, layout engine, Grid support, native boundary, tests, examples, and paired documentation into the independent Ebox repository. Keep ETAF and application concerns outside this package.
