about
nx_fpsmeter.nx -- sovereign rolling FPS meter: count the frame timestamps within the last 1000 ms. The call
stack currently measures NOTHING (can't answer "what fps are we at"); this is the instrument ("monitor the
system" law). State m[*i64]: [0]=head, [1]=count, [2 + i]=timestamp ring (FM_CAP). Assumes a real ms clock
(sys_now_ms). Pure buffer ops -> wasm-friendly (client) AND daemon-reusable. license_tier: ORIGINAL
