TV Static Channel Surf

Make [TEXT] appear while someone flips through analog TV channels. Start on full-frame black-and-white static snow with a big green on-screen channel number in the top-right corner. Step up a channel every half second or so: one channel shows a picture rolling vertically through the static, another shows [TEXT] torn into diagonal bands by lost horizontal sync, with static in between. Then the channel tunes in: [TEXT] in a chunky signage-style display face, bright yellow with a dark drop shadow on deep teal, rolls once and locks, keeping a faint ghost copy offset to the right, light snow, a soft herringbone interference pattern and slight line jitter. Hold for four seconds, then flip back to static and loop every 8 seconds.
