Three cross-referenced markers — config.h, operation.h, and FW-10 in the
test file — calling out that the FETCH_INTERVAL_MS cap is intentionally
holding the polling rate at 1 minute for dev iteration. Once the firmware
is stable and we want the device to honor the app's per-frame
rotationIntervalMinutes / wakeHour settings, the cap in operation.h
becomes a sanity-clamp (e.g., 30 s ≤ sleep ≤ 25 h) and the no-header
fallback splits into its own constant.
Behavior unchanged — comments only.
