砖墙上闪烁的霓虹猫

Create a 6-frame neon sign animation sprite sheet, 3 columns by 2 rows of equal 512x512 cells. Background: the same dark brick wall in every cell, at night. Subject: an original neon tube sign shaped like a sitting cat outline in hot pink with a cyan tail, mounted at the same position. Lighting sequence: fully lit, fully lit, the tail flickers off, both dim, fully lit with a strong glow, tail on and body slightly dim. Only the brightness and glow on the wall change. Frame 6 returns to frame 1. No grid lines, no numbers, no text, no letters, no logo.
