// Compatibility coverage for profile-specific server-to-RCT calibration.
//
// Scope: ensure the calibrated MJPEG and HEVC ingress profiles both cover every
// supported UVC mode.
// Targets: server/src/calibration/profile_offsets.rs and
// scripts/manual/run_server_to_rc_mode_matrix.sh.
// Why: the HEVC path decodes and re-encodes before UVC, so it must never
// silently borrow the MJPEG timing map unless explicitly asked.
