Settle the cast toolchain (STYLE.md #9) and build the demo pipeline end to
end. Driver: autocast, chosen by spike — its !Interactive feeds keys to the
running TUI and captures the redraw, the right model for a full-screen
crossterm app. asciinema-automation was rejected (assumes shell echo/\n Enter;
produced a garbled cast against the TUI).
- add asciinema-player; Cast.astro (player island) + Demo.astro (the WASM-swap
seam, ADR-website-001 §3)
- casts-src/: human-readable command-lists (casts.mjs) + generate.mjs, exposed
as `pnpm casts`; expands steps to autocast YAML and records to public/casts/.
Command-lists are the durable source; .cast files are regenerable (final
re-record sweep due once the app is locked).
- quickstart.cast (create -> add columns -> insert -> show data) embedded on
the landing page above the feature cards.
Verified: pnpm build clean (25 pages); player + cast bundled and served;
landing HTML references the cast. Visual playback check pending (no headless
browser here — verify via dev server over the tunnel).
