Crate pepl_ui 

PEPL UI Component Model

10 Phase 0 components: platform-abstract, accessibility-first, deterministic rendering. Components produce Surface trees — the host’s View Layer renders them.

Architecture

PEPL view function → evaluator builds SurfaceNode tree → Surface → JSON → host renders

Phase 0 Components

Category	Components
Layout	Column, Row, Scroll
Content	Text, ProgressBar
Interactive	Button, TextInput
List & Data	ScrollList
Feedback	Modal, Toast
