/**
 * Dev-only VIGNETTE flow test: boots straight into the GameScene (smoke
 * style), lands on the home world, then drives the SHIPPED bar scene —
 * 'Special Delivery' step 1 (data/vignettes.json → special_delivery_bar_meeting)
 * — end-to-end. The dialogue, the voices, and the quest gate are the
 * authored ones; the test injects only the one thing the home world lacks
 * by design — a BAR clip (the bar service normally rides the neutral
 * capital's frame, where the scene's home is).
 *
 *   node dev/server.mjs 8124
 *   node dev/cdp-firefox.mjs http://127.0.0.1:8124/dev/vignette-flow.html \
 *     'return window.__VIGNETTE_TEST__;'
 *
 * Steps:
 *   1. boot + the fixtures (the bar clip on the home frame; the quest
 *      granted — 'Leaving the Nest' is claimed in the story chain, which
 *      the smoke boot does not walk)
 *   2. land (the real entry) → force the surface stage
 *   3. the hub is live + the scene is DUE (the gate's facts hold: the
 *      quest's step 0 is the 'vignettePlayed' witness — open until the
 *      scene completes)
 *   4. enter the bar — the scene ARMS (pending), not open yet (the
 *      opening beat: the location's clip reads first)
 *   5. the beat lands — the window opens on TRESTLE's line (the deck
 *      stood down); the feed is the FULL 256×256 planet cut and the
 *      window sizes itself to the line (button below the text, inside
 *      the window — the probe measurement matches the engine's live one)
 *   6. NEXT ×4 — each of Carol's four beats (the face stays CAROL; the
 *      voice is the line's own clip, ducking the hum), verbatim words,
 *      and the window re-sizes to each (taller) line
 *   7. the last line reads DONE; the press completes: the STORY BEAT
 *      runs (the hold builds out to 4 bays — the scene's effects — and
 *      the 'special-package' joins the hold; its presence stands the
 *      'cargoUpgraded' step done), the ledger marks (completing), the
 *      quest's bar step stands DONE (the witness), the quest is not yet
 *      claimable (its delivery step still stands), the bar's own lock
 *      returns — and LEAVE BAR, which the scene's lock had disabled,
 *      re-arms (the press leaves the bar), and the music duck is
 *      restored (it was ducked per-sound under every voice)
 *   8. re-enter the bar — the scene stays spent (the once-ledger), a
 *      plain visit with no window
