Module render 

Ratatui rendering — draws buffer pane + status line each frame.

Chrome colors are the Vellum fleet theme (warm aged-paper Nord-matte) — every value is a BORN ishou_tokens::VellumPalette token, so the TUI chrome matches the rest of the fleet (mado, tear, frostmourne, …) and the GPU backend.

Functions

draw_frame

Draw one frame. Call from within terminal.draw(|f| draw_frame(f, state)).
