  "anatomy": {
    "coordinates": "Source glTF spatial relationships and Y-up orientation preserved. Selected meshes are centred and uniformly scaled together for display. No independent registration or clinical validation was performed.",
    "selection": "Labelled cortical gyri, hippocampi, amygdala groups, hypothalamic zones, anterior pituitary, cerebellar and brainstem context; vascular and white-matter tract meshes are omitted. Anatomical labels are inherited from their named parent nodes when primitives carry no labels.",
    "dmn": "Illustrative anatomical territories, not a functional parcellation or activity/connectivity dataset. Medial prefrontal territory is selected from source superior frontal triangles with mean abs(source-world x) < 0.012 m and mean anterior source-world z > 0.018 m. Posterior cingulate, precuneus and angular gyri are gross labelled anatomical territories. Their complete anatomy is not exclusively DMN.",
    "amygdala": "Four grouped subdivisions per hemisphere from the source CIT168-derived registration; source reports ~7 mm held-out registration error. Fine functional localisation is not justified.",
    "hypothalamus": "Atlas-derived coarse zones, not a resolved paraventricular nucleus. Anterior pituitary is anatomical context. Adrenal glands are not modelled."

  "presentation": {
    "viewer": "Three.js 0.187.0, local Draco decoder. Heavy code and anatomy load only when the user opens the guide.",
    "preview": "On pointer hover or keyboard focus, 15 anatomical display groups are translated into rows ordered by projected bounding footprint; leaving restores the source positions. Cortical territories stay with their hemisphere, and amygdala subdivisions remain grouped. A local WebP frame atlas drives a 2D canvas, independent of video autoplay or seeking. Camera and CSS display scale stay fixed throughout. For the separated display only, every anatomical group is uniformly reduced to 62% around its own centre and translated into the layout; all groups use the same factor, preserving their relative size and shape. Returning restores their original scale and positions. This is an illustrative layout, not anatomical motion, connectivity, activity or treatment response. Source geometry and each group’s internal spatial relationships remain unchanged. Reduced-motion or low-data preferences use matched stills.",
    "preview_licence": "CC BY-SA 4.0",
    "encoding": "61 forward poses in a 6-column, 11-row transparent WebP atlas, 640×360 per frame; on-demand hover download only. Continuous reversible progress selects the separation/reassembly pose over approximately 1.25 seconds per direction. CSS scale is fixed at 1.4; there is no hover zoom. Canvas is cleared before every transparent frame. The larger assembled framing uses the identical render for the poster and first atlas pose, with matching bounds, object-fit and transform origin. Earlier preview assets are retained as historical media and are not loaded by the current card.",
    "intro": "On first entry, mesh groups briefly assemble from an exploded arrangement into the deposited relative positions. Only group translations are animated. Interacting cancels the intro and restores anatomy; reduced motion skips it."
