Model-sheet callout lines — Model-sheet callout lines Like a model sheet, put the full figure on the left and stack four wide rounded windows on the right, every other one shifted 8% to the right, each with a monospaced number such as ": 01" and the part's name beside it. Make the section 300vh tall and the box inside a 100vh sticky element. Each window shows part of the same figure: an SVG `<use>` cropped by the window's own viewBox and stretched to fill it with `preserveAspectRatio="xMidYMid slice"`. Window i opens from the left with `clip-path: inset(0 X% 0 0)` and slides in 48px from the right while --p goes from 0.06 + 0.18i over 0.18. Starting 0.08 later, draw a `pathLength="1"` line with `stroke-dashoffset` from a point on the figure (0–1 coordinates of the picture) to the middle of the window's left edge, with an accent dot at the point. Re-measure both ends from the elements on every draw. Implement with CSS and plain JavaScript only; do not use a library. Do not drop: - Measure the line ends from the elements on every draw; fixed coordinates miss the windows at other widths - Each window is a crop of the same picture, so the line and the close-up always agree - With reduced motion on, show every window and line at once and stop A working example (one self-contained HTML file): https://design-vault.pages.dev/designs/motion-callout-lines/demo.html
