`static/arthur/js`, where `shadow-cljs` already writes it — so nothing copies files
between the two.
### Paint sketch
Click **new polygon**, place at least three vertices on the stage, then click
**finish shape**. Select a shape to drag its vertices. Scrub to another frame and
click **new drawing key** to copy the visible outline there; the previous drawing
holds until that key. The numbered drawing-key buttons jump to editable keys.
The transition control between two drawing keys can switch that gap between a
hold and linear vertex tweening. Other gaps keep their own timing. Tweening works
best when the same vertex
keeps the same meaning in every drawing. Paint shapes use the timeline clock
directly, so the roto exposure grid does not delay a drawing key or step its
tween. Use the project **save** button to persist the drawings.
`/index.html` still works, and that is deliberate: it is the URL the browser suite
has used since step 5, when shadow-cljs's `:dev-http` did no directory-index
resolution and the suite learned to ask for the file.
