feat: add FPS throttle to reduce CPU/energy usage - #10
Merged
Conversation
The detection loop was running uncapped, consuming maximum CPU. Add a --fps flag (default 10) with a throttle_fps() helper that sleeps the remaining frame budget each iteration. Also fix double apply_night_mode on motion frames — snapshots now only apply CLAHE when --snapshots is enabled instead of unconditionally.
