//
// readBarometer() is false when the chip has no new sample ready or hands back a
// pressure outside the DPS310's own 300..1200 hPa range. The sensor converts
// slower than the control loop runs, so a false return is routine - about a
// third of calls - and means "nothing new this cycle". Do not build a health
// check on a single one. It also cannot detect a chip that is still producing
// plausible-looking but wrong numbers; nothing in this firmware can. See the
// notes in barometer.cpp.
