Create docs/demo.tape scripting a ~15s pivot axis reassignment demo.
Hide shell startup and quit so the GIF opens directly on the TUI.
Set up git-lfs for docs/*.gif. Merge LFS hooks with existing beads hooks.

Audited SPEC.md against code — mostly accurate but redundant with
repo-map.md and design-principles.md. Minor drift in storage internals,
wizard step count, and mode representation. Salvaged product vision and
non-goals into docs/design-notes.md with staleness disclaimer.
