Covers the end-to-end flows per slice: markers (m shortcut + scrub- ruler interactions), script tracks/frames (open dialog, action types, forward-only firing rules), button clip creation and drag-to-track, ButtonInstance dialog (label, onClick, disabled, transitions), canvas runtime (pointer state machine, drag-out cancel behavior, scripted state flips), transitions (matched layer blend vs crossfade, easing), the DSL language reference with examples, a quick sanity pass for the HTML export runtime, and which in-app test suites to look for. Also documents the two known limitations (no in-app button state authoring, scripts not baked into the server PNG/MP4 render) and a small devtools cheat sheet for poking the pinia store directly.
