  "notes": [
    "Each zip contains a ParaView .pvd collection and latest-time legacy VTK volume snapshots for shell, tube, and solid.",
    "The MP4 is the inline recording of retained outlet monitor telemetry; the GIF is the browser fallback. Neither is a time-resolved 3-D field animation.",
    "The .pvd bundles remain the interactive ParaView field views.",
    "The flowlines package is a separate time-indexed post-processing of the unchanged v7 U fields at 0, 200, 400, 600, and 800 s; its .pvd opens in ParaView and its MP4/GIF is a true field-derived animation.",
    "The amplified flowline recording uses a fixed baseline-relative delta-speed color scale (±10% for display only) to make subtle changes easier to see; it does not alter the solver fields.",
    "The smooth amplified recording interpolates rendered colors between the five retained snapshots for readability; intermediate frames are not additional solver time steps.",
    "The flow-entry recording progressively reveals the retained t=800 s streamlines from the inlet toward the outlet; it is a presentation aid, not a zero-initialized solver transient.",
    "The combined story recording places flow entry, retained solver-time streamlines, and a fixed-scale thermal-gradient view into one browser-playable sequence.",
    "These are derived visualization artifacts, not physical validation or design-readiness evidence."
