// The exact inverse of the field offsets in triton.h (s16off/u16off/trigU8/btnsOf/imuFrom45). The
// puck's rf_link.cpp decodes this same byte layout, so the round-trip Deck -> g_in -> 0x45 -> puck ->
// Steam is symmetric. Output is REPORT45_LEN bytes: [0x45][seq][buttons u32][...sticks/pads/IMU].

// IMU tail at rep[34..46] that rf_link decodes when tlen >= 46).

// Build a fresh report 0x45 from g_in into out[REPORT45_LEN]. seq is the rolling frame counter
// (rep[1]); the puck treats a changed seq as a fresh report.
