//
// Frame synchronisation for FT8 and FT4.
//
// Provides:
//   - `ft8_sync` — search an IQ buffer for FT8 frames, return soft LLRs
//   - `ft4_sync` — search an IQ buffer for FT4 frames, return soft LLRs
//   - `Ft8SyncResult` / `Ft4SyncResult` — per-candidate decode inputs
//   - `Waterfall` / `compute_waterfall` — low-level spectrogram (exposed for testing)
//   - `Candidate` — sync candidate (time_sym, freq_bin, score)
