PODIUM — four brand stages on one podium (ports of the three.js stage kit: astra / nexora / lumen / verde). Scale: 1 kit unit = 100 mm. Podium top r=205 mm at y=54; camera 1200 mm back, eye 210, look_at (0 235 0), fov 42 (verde: 740 back, eye 155, look_at (0 180 0), fov 34). Mouse parallax → slow drifting camera keyframes, fixed look_at. Sky dome / cyclorama shaders → gradient background + drifting haze lobes + fog; halos, anamorphic streaks and beams → haze sprites; god rays → ray; ray-arc rings → emissive tori (lower half sunk under the floor = arch); Reflector floor → reflector-ground; TextGeometry → text3d (same helvetiker faces); extruded sparkle/chevron/leaf shapes → extruded-path. Scene map: astra 0–12 → nexora 12–24 → lumen 24–36 → verde 36–48 — `match` transitions morph the shared podium parts, floor, title and tagline between stages.

    PODIUM — four brand stages on one podium (ports of the three.js stage kit: astra / nexora / lumen / verde).
    Scale: 1 kit unit = 100 mm. Podium top r=205 mm at y=54; camera 1200 mm back, eye 210, look_at (0 235 0), fov 42
    (verde: 740 back, eye 155, look_at (0 180 0), fov 34). Mouse parallax → slow drifting camera keyframes, fixed look_at.
    Sky dome / cyclorama shaders → gradient background + drifting haze lobes + fog; halos, anamorphic streaks and beams → haze
    sprites; god rays → ray; ray-arc rings → emissive tori (lower half sunk under the floor = arch); Reflector floor →
    reflector-ground; TextGeometry → text3d (same helvetiker faces); extruded sparkle/chevron/leaf shapes → extruded-path.
    Scene map: astra 0–12 → nexora 12–24 → lumen 24–36 → verde 36–48 — `match` transitions morph the shared podium parts,
    floor, title and tagline between stages.
