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.

Built with application teams

Teams use the same typed vocabulary across engineers, coding agents, and production Rails code.
