Canon R5 II and R1 Get Action Priority and Register People Upgrades

If you shoot sport or events on an R5 II or R1, pull this update before your next job. The Register People Priority fix is the one that actually matters for working photographers: it now handles profile views, obscured faces, small subjects, and kids in frame. Those are exactly the conditions that killed confidence in the feature at launch. The American football addition is niche if you're not shooting gridiron, but the underlying helmet-and-shoulder-pad detection improvement tells you Canon is tightening subject recognition across the board. Custom button assignment for pre-burst is a small thing that removes a real friction point mid-shoot. Quietly useful across the board.
