1//! Synchronous full-screen presentation over terminal command primitives.
2//!
3//! [`Screen`] owns frame history and transactional presentation. It borrows a
4//! draw-scoped [`Frame`] to callers, lowers changed cells through
5//! [`urushi_terminal::CommandWriter`], and advances its committed baseline only
6//! after output and flushing succeed. Physical terminal connection, input,
7//! queries, raw mode, and session restoration remain responsibilities of
8//! [`urushi_terminal::TerminalBackend`] and higher-level callers.
