A filmstrip with a spring-loaded playhead (k=90, c=16, ζ≈0.84 — one soft overshoot): hover or drag the strip and the large preview crossfades ⌊p⌋ into ⌈p⌉ by the fractional part, with frame ticks and a monospace timecode. Scrubs itself at 0.9 frames/s when idle. The strip is a real slider with arrow/Home/End keys.
