"""gr-rylr998: GNU Radio OOT module for RYLR998 LoRa modems.

Provides complete TX/RX blocks for RYLR998 LoRa modems with support for
the reverse-engineered NETWORKID → sync word mapping.

Blocks:
    - css_demod: CSS demodulator (FFT peak detection)
    - css_mod: CSS modulator (chirp generation)
    - frame_sync: Preamble + sync word detection
    - frame_gen: Header + preamble + SFD generation
    - phy_decode: Gray decode → deinterleave → Hamming → dewhiten
    - phy_encode: Whiten → Hamming → interleave → Gray encode

Utilities:
    - networkid: NETWORKID ↔ sync word conversion
