    Variable WARM_FIRING_COST_MSConst

    WARM_FIRING_COST_MS: 79

    What one warming firing costs, in the same units as COLD_BOOT_MS.

    Not a duration (an idle object waiting on an alarm is not billed for duration); a firing spends a request and a row. Derived from the measured ~505 renders/day crossing: P(render within 10 s) there is 0.05678, and break-even P x COLD_BOOT_MS = C_warm gives 79.
