The ESP32 BMP280 example compile was timing out at 98% (1473/1483 build
steps), failing with the unhelpful "ESP-IDF build timed out (300s)"
message even though every individual step was healthy.
Cold ESP-IDF builds that pull in external Arduino libraries — Adafruit
BMP280 + Adafruit BusIO + Adafruit Unified Sensor on top of the base
arduino-esp32 component tree — routinely produce ~1480 build objects.
On modest VPS hardware this takes 5-7 minutes the first time. Ninja's
incremental cache makes subsequent compiles seconds, but the first one
needs more headroom.
Constant lifted to NINJA_TIMEOUT_S so the value used in the timeout
matches the value reported in the error message — the previous code
hard-coded "300s" in two places that were free to drift apart.
Repro before: open the example "ESP32 — BMP280 Barometric Pressure"
on velxio.dev/editor on a clean container, click compile → fails after
5 minutes with timeout. After: completes in ~6 minutes on the first
run, ~5 seconds on subsequent runs.
