Normalize size units and intrinsic sizing across Elisp and native layout. Add help, pointer, hover-style and keymap support with reusable interaction adapters. Keep content updates local, preserve scroll caches and hover borders, and avoid rebuilding retained plans and ownership metadata for stable geometry. Validation: make check and native-rust-tests passed; targeted native interaction and scroll publication regressions passed.
