  "_summary": "Simulator budgets checked by `make perf` and `make memtest` (README section 18).",
  "_about": "Simulator timings depend on your PC. startup_ms (in-app, object creation to first full frame) measured 1-18 ms in M4; its budget leaves room for simulator jitter. first_frame_wall_ms includes the JVM start of monkeydo, loading the glance, the 2 s pause and the tap that opens the app (16-18 s in M4), so it only catches big regressions; set to about 2x. Memory is a hard limit: at most 70 % of the watch-app memory of the device, and 70 % of the glance's 64 KB.",
