CRT Power On / Off

Show [TEXT] on an old cathode-ray tube TV that switches on and off. The screen starts dark gray glass with a soft reflection. A tiny white-hot dot appears in the center, stretches into a thin horizontal line, then the picture opens vertically, overbright and slightly blurry, and settles over a second. The picture: [TEXT] in a heavy geometric sans with a hot pink to amber to cyan gradient, glowing over a deep teal-black field. Bulge the glass with barrel curvature, darken the corners, add fine scanlines, an RGB stripe mask, phosphor bloom and a faint slow hum bar. Frame it in a rounded charcoal bezel. After a few seconds collapse the picture into a bright line, then a dot that fades with afterglow; loop every 8 seconds.
