Three more casts on "doing" pages:
- first-project reuses the quickstart cast (the create→insert→show tour)
- modes (new): a simple command, then `mode advanced` where the same command
also prints "Executing SQL: …" (the teaching echo — "learn the SQL underneath")
- undo-redo (new): insert two rows, `undo` (Y-confirm modal) backs one out,
`redo` restores it
Also fix the cast endings (review feedback): scripts ended by typing a `quit`
command, which — once the trim drops the shell exit — left a dangling "quit" in
frame with no payoff. End every cast with Ctrl-C instead (the app's quit key,
KeyCode::Char('c')+CTRL): it types nothing, so the cast ends cleanly on the
last content frame. Generator gains a `CtrlC` key; all six casts regenerated.
Convert the three pages to .mdx and embed. Build clean (26 pages); 6 casts.
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.
The previous commit captured only the .md→.mdx rename — a botched `git add`
(a stale .md pathspec aborted the whole add) dropped the actual content. This
adds it:
- casts.mjs: the assistive-editor cast definition (Tab completion → the [ERR]
validity indicator catching a misspelled table → friendly error → corrected
command). Behavior verified by a throwaway spike before scripting.
- public/casts/assistive-editor.cast (generated via `pnpm casts`)
- embed the cast under the intro on the assistive-editor page
Verified: pnpm build clean (25 pages); cast bundled, served, and referenced.
Visual playback check pending (verify via dev server/tunnel).
