When KOBO_BENCH=1 is set in the environment, the game becomes a
hands-off benchmark:
* Skips the intro/menu sequence and pushes st_game directly with
scene=0, skill=CLASSIC, invulnerable ship, always_fire = constant
auto-fire, countdown = 0 so "GET READY" auto-pops in 700ms.
* Seeds pubrand and gamerand from KOBO_BENCH_SEED (default 12345)
so the map, stress spawn pattern, and enemy AI are identical
run-to-run.
* Defaults KOBO_STRESS=1500 unless overridden, so the move pass has
a steady workload, and KOBO_PROF=1 so the profiler is on.
* Counts frames in run_game; after KOBO_BENCH_FRAMES (default 1800)
it dumps prof to stderr and exits cleanly.
Usage from repo root (the cwd matters — relative GFX paths only
resolve from here):
KOBO_BENCH=1 ./build/kobodl 2>bench-logs/phaseN.log
A single command produces a comparable profiler dump at every phase
of the DOD refactor — no menus to navigate, no keyboard input,
identical workload.

// Deterministic, hands-off benchmark mode.

// Activated by KOBO_BENCH=1 in the environment. When on, the game:
|
|
// * skips the intro/menu sequence and drops straight into stage 0
|
|
// * seeds gamerand and pubrand from KOBO_BENCH_SEED (default 12345)
|
|
// * enables cmd_indicator (collisions register but neither side takes
|
|
// damage — true invulnerability for deterministic workload),
|
|
// cmd_cheat (skip score recording), and always_fire (auto-fire)
|
|
// * defaults KOBO_STRESS=1500 unless overridden, for a steady workload
|
|
// * dumps the profiler table and exits after KOBO_BENCH_FRAMES
|
|
// run_game frames (default 1800 = ~60s at the game's tick rate)
|
|
//
|
|
// Together this makes a single command (`KOBO_BENCH=1 ./kobodl`) produce a
|
|
// reproducible profiler dump across phases — no menu navigation, no keyboard
|
|
// input, identical RNG and spawn pattern run-to-run.
