- The polled position is also the composite-blend position: at 16 ms a
240 fps session reused a stale position for ~4 consecutive frames and
the composited pointer visibly stuttered against the video. 4 ms
out-paces every session rate; a tick is one GetCursorInfo syscall.
- Log the queried DISPLAYCONFIG_SDR_WHITE_LEVEL scale on each blend-
scratch rebuild so an HDR session shows what is actually applied
(the virtual display's own SDR-brightness setting is the suspect
when the cursor still reads dark).
