    isReducedResolution: boolean
    nativeDPR: number
    dprFloor: number

    Lowest DPR scaleDown will accept right now (tightens via U-shape probes).

    probing: boolean

    True while a scaleDown move is being verified for U-shape improvement.

    refreshRateCap: number

    Estimated achievable rAF rate the FPS thresholds derive from.

    dprCeiling: number

    Effective scale-up ceiling: the lower of the session ceiling (the display's DPR, capped unless high DPR is allowed) and a LEARNED 1.0 demotion after repeated punished ascents.

    allowHighDPR: boolean

    Whether the viewer may currently render above CSS resolution.
