Address cast review feedback:
- Trim every cast to the in-app region (generate.mjs): the recording now
starts with the app already running and ends on the last in-app frame —
drops the `$ rdbms-playground` launch and the return-to-shell frame (the
latter was the stray cursor-under-$ artifact). Opt out per cast with
`keepShell: true` for demos that document the CLI launch.
- Landing quickstart cast: autoPlay + loop, with a 2.5s hold on the final
frame so it pauses before restarting.
- Cap the demo at max-width 46rem and centre it, so the player (fit:'width')
no longer scales its font up to the full splash column.
Casts re-recorded via `pnpm casts`. Build clean (25 pages).
Tab-keypress visibility deferred to an in-app overlay primitive (filed as
issue #22 — also serves the planned guided-lesson system); the cast notes
Tab in its caption for now.
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).
