| 1 | //! Coherent shell grammar for the underwater TUI. |
| 2 | //! |
| 3 | //! This module owns phase, responsive density, the empty-state composition, |
| 4 | //! and the compact header/footer fact budget. Product data still belongs to |
| 5 | //! [`App`]; this is only its terminal projection. Keeping these decisions in |
| 6 | //! one place prevents the default UI from drifting back into a header + |
| 7 | //! sidebar + dashboard + footer composition with four owners for one fact. |
