Image: Widescreen 16:9 game battle background MASTER COMP

Generated from: Widescreen 16:9 game battle background MASTER COMPOSITE for a turn-based JRPG. Father's alchemy laboratory arena in an underground Noctari city. Style: hi-bit HD-2D painted environment like Octopath Traveler II / Sea of Stars — crisp readable shapes, painterly depth, NOT soft AI mush, NOT photoreal, NOT cyberpunk. PALETTE LOCK (critical): deep teal-black stone walls, warm brass instruments and railings, amber lantern light pools, wet dark stone floor with subtle reflections. ONE violet Core crystal on a pedestal in the far midground as a small accent only. Cool hologram cyan rim light on glass flasks. DO NOT flood the scene with purple/magenta neon. Purple is a tiny accent only. COMPOSITION for turn-based combat: wide open horizontal stage across the lower-middle third for party (right) vs enemies (left). Clear empty center so character sprites read. Architecture frames left and right edges. Ceiling arches and hanging brass lanterns. Dust motes in amber beams. Epic but intimate lab, not a megacity. Camera: slight side view, flat enough for 2D sprites. No characters, no UI, no text, no watermark.
