Long-Exposure Light Painting

Create a long-exposure light-painting animation of [TEXT]. At night, over a dark hill silhouette under faint circular star trails, a bright sparkler writes [TEXT] in one continuous, slanted, monoline cursive stroke at natural handwriting speed. The camera's long exposure keeps the whole path visible as a glowing ribbon: a hot white core with an orange glow shifting to pink along the word, brighter where the hand slowed down. The sparkler sheds a shower of short golden sparks whose streaks also stay frozen in the exposure. When the word is finished the light switches off, travels back and dots the i's and crosses the t. Hold the finished photograph, then fade it to black and loop.
