Dynamic-importing @hermes/ink + App costs ~170ms on cold start — during that window the terminal was blank. Now `entry.tsx` writes a raw-ANSI banner to stdout immediately after the TTY check, using hardcoded DEFAULT_THEME colors. Ink's `<AlternateScreen>` wipes the normal-screen buffer when it mounts, so the boot banner is replaced seamlessly by the real React render a moment later — no double-banner, no flash. T=2ms banner visible (vs. ~170ms before) T=~170ms React + Ink mounts T=~200ms alt screen takes over, Banner component repaints Palette drift between `bootBanner.ts` and the live theme is harmless — the live render overrides after ~200ms. Narrow terminals (cols < 98) fall back to the one-line "⚕ NOUS HERMES" marker.
