Chalkboard

2  "name": "chalkboard",
3  "voice": "night lecture — the lower third is a worn deep-green chalk band where every word is SCRIBBLED in fast chalk (2-frame pop + scribble reveal + dust puff, seeded crooked), emphasis gets double underline dashes and the final word lands in yellow chalk; between sentences an ERASER SWIPE smears the old words off and leaves ghost smudges. At the apex the band grows into a full blackboard behind the subject and the hero word is HAND-WRITTEN 130px tall in chalk stroke by stroke (jittered nib, dust falling from the pen), finished with a hand-slap dust clap and two violent underlines, then the halo breathes.",
4  "when": "education/explainers, science and lecture content, teacher channels, documentary asides, 'professor energy' brand spots. Reads as handwriting, so it suits thoughtful pacing; the deep-green board supplies its own contrast on bright scenes.",
