    "Which parts of Steam's UI pop out of their window in stereo depth (native mode, docs/NATIVE.md).",
    "Read by device/lgs_layers.js; tokens %{Name} resolve like theme CSS.",
    "Per surface: key (exact overlay key) or keyPrefix (pooled popups; the surface is then reported as NAME.<id>),",
    "  cover = the element whose rounded box glassd fills with this surface's glass (material), hiding Steam's panel there;",
    "  with all: true every outermost match is a shape of its own (bar segments, a popup's cards), never one box around them,",
    "  frameKey = only while the dashboard frame showing that overlay is visible, laserOnly = only in laser (not controller) mode.",
    "Per layer rule: sel, optional pseudo (::before/::after: the capsule is that pseudo-element),",
    "  dz = depth toward the viewer in metres, lift = extra dz while focused (focus selector, default .gpfocus/.gpfocuswithin;",
    "  'always' when sel already only matches focused elements), outset/inset in CSS px, r = 'capsule' | CSS px | computed radius,",
    "  max = elements per rule, material = slab material (liquid, panel, thick, window).",
    "Layer ids are slots: a rule's first element is reported as the rule id, later ones as id.1, id.2 (the id follows the match).",
    "Rules are in priority order: a layer that overlaps one kept earlier is dropped, as are covered (under a scrim),",
    "transparent, clipped-away and offscreen ones, and, while their scroller scrolls, the ones that move with it.",
    "Content (lists, grids, text, art) stays on the window plane; only ornaments, floating controls, menus/sheets",
    "and the focused card pop. Never glass on glass: a cover shape is not also popped. Keep each surface under 24 layers."
