The 320-figure crowd does the wave. **Semifinal — Dusk.** Sky lerped orange. VENGEANCE-X meets ARTEMIS. Mid-fight, the WEAPON cam zooms on the saber. VOX (gold chyron): *"Watch this — she's charging the LIGHTNING SLASH!"* Full-screen flash cut-in: **"LIGHTNING SLASH"** in 200pt katakana-styled font. ARTEMIS staggers. HP bar drops to red. KO banner. Bracket strikethrough. **Final — Night Sky.** Skybox is black with stadium spotlights pulsing. VENGEANCE-X vs PHANTOM. PHANTOM teleports behind. *"PHANTOM SHIFT!"* Full-screen flash. Saber clashes. IMPACT cam catches the parry sparks. PHANTOM down. Bracket locks. **"CHAMPION: VENGEANCE-X."** Confetti. The mech rotates center-stage. 12s. Reset. New 8. Loop.

What I learned shipping it

Sky progression (day → dusk → night) tied to tournament round is the cheapest way to make a single-arena tournament feel like an EPIC tournament — no new geometry, just a `sky.color.lerp()` synced to bracket progression.

Super-attack full-screen flash cut-ins with signature move names ('LIGHTNING SLASH', 'PLASMA STORM') are the anime-broadcast hook — they freeze the action, fill the screen with the move name, then resume. Costs nothing, sells the spectacle.

A tournament bracket as state machine (INTRO → MATCH_INTRO → FIGHT → SUPER_A/B → KO → BRACKET_UPDATE → CHAMPION → RESET) keeps a 12-fight tournament under 6 minutes by compressing each fight to ~30s — perfect for a Twitch chunk.
