# /read-along : the guided storybook walkthrough Version 5 (2026-07-18). Prior versions preserved beside this file (v1.md through v4.md). v2: port safety, artifact demos, in-tour honesty, keepsake print. v3: demo-prep bound, renderer aim, fatigue adaptation, verbatim transcript export. v4: the export menu, archaeology and divergence scope modes, audio narration, narrate-only mode. v5 (all export refinements, operator-driven): exports land in the operator's Downloads folder by default with the destination path ALWAYS named in the confirmation; the Markdown twin as the post-processing substrate; the black-on-white print palette; export discoverability in the first parking line. v5.0.1 (2026-07-19): the in-page audio player no longer treats the reading area as a play control - clicking, selecting, or scrolling story text never starts or stops the voice; all playback lives on the pill, and resume picks up where it paused (the two-cursors rule, see audio-player.md and the README design notes). Also: cross-platform Chrome launch (Windows form primary, macOS/Linux equivalents noted). The operator's framing: the childhood read-along record book. A storybook page they read, live pictures that move (the real product driven in a real browser), a bell that tells them when to turn the page, and a host who welcomes interruptions and always lands the story back on its feet. Target 5 to 15 minutes of reading: 5 to 9 stops, most important first. Mark Twain rule: a short walkthrough takes MO
