- entry.tsx no longer writes bootBanner() to the main screen before the alt-screen enters. The <Banner> renders inside the alt screen via the seeded intro row, so nothing is lost — just the flash that preceded it. Fixes the torn first frame reported on Alacritty (blitz row 5 #17) and shaves the 'starting agent' hang perception (row 5 #1) since the UI paints straight into the steady-state view - AlternateScreen prefixes ERASE_SCROLLBACK (\x1b[3J) to its entry so strict emulators start from a pristine grid; named constants replace the inline sequences for clarity - bootBanner.ts deleted — dead code
