   Atmosphere layers (back to front):
     .ambient  — the playing video, redrawn at ~1/12 scale and blurred: light, not picture
     .shade    — vignette and depth darkening
     content   — glass panels, viewfinder monitors
     .pblur    — progressive blur at the viewport edges (stacked backdrop-filter bands)
     .grain    — animated film grain over everything
