The clips were silent screen captures - the user's actual ask was for someone talking
through what's happening. Each clip step now carries a narration line synthesized
offline via espeak-ng; the recording paces itself to each line's real spoken duration,
and the final audio track is built from the real measured per-line start times (adelay +
amix) so narration and on-screen action stay in sync over a 30+ second clip instead of
drifting against an idealized schedule.

CDP screencast -> ffmpeg -> MKV, driven against the same isolated server/browser pattern
the test suite already uses. Recorded three short clips demonstrating this session's tab
and schedule features; output goes to the gitignored video-guides/ folder rather than the
repo since these are sizeable binaries.
