Typed Ruby components

Closed Phlex APIs make component vocabulary explicit and verifiable.

Static, themeable CSS

Gem-owned styles use documented custom properties without runtime compilation.

Rails-native forms

Model values, errors, names, multipart behavior, and submission semantics stay intact.
