    // The vocabulary aimed at ONE shot: go from the whole browser window down
    // to the pixels of a single button, at a grazing angle, and let depth of
    // field carry the distance.
    // 0.0 to 1.4    the establishing pose, nearly deep focus
    // 3.0 to 5.2    the whole window, from the side — offset parks it right
    // 7.0 to 9.2    the sign-in card
    // 11.0 to 13.0  the password row
    // 14.8 to 16.6  the button — 90 mm out, on a 50° lens
    // 18.2 to 20    back out to the window

    // The auto-injected DOF pass is appended to the END of this chain, and the
    // generic promo composer has no OutputPass — a chain that terminates in a
    // raw ShaderPass hits the canvas LINEAR and the whole frame reads far too
    // dark (measured here: a #0f151f page came back as rgb 1,2,3). film_grain
    // carries the ACES + linear→sRGB transform itself, so it does the output
    // duty. This reel needs a <postprocessing> block BECAUSE of the DOF.
    // DOF scenes lose MSAA (the composer target is non-multisampled), so FXAA.
