// ===== RAS-2819T PROTOCOL DOCUMENTATION =====
//
// The RAS-2819T uses a two-packet IR protocol with some exceptions for simple commands.
//
// PACKET STRUCTURE:
// All packets are 6 bytes (48 bits) transmitted with standard Toshiba timing.
//
// TWO-PACKET COMMANDS (Mode/Temperature/Fan changes):
//
// First Packet (rc_code_1): [C2 3D] [FAN_HI FAN_LO] [TEMP] [~TEMP]
// Byte 0-1: Header (always 0xC23D)
// Byte 2-3: Fan speed encoding (varies by mode, see fan tables below)
// Byte 4: Temperature + mode encoding
// Byte 5: Bitwise complement of temperature byte
//
// Second Packet (rc_code_2): [D5] [FAN2] [00] [SUF1] [SUF2] [SUF3]
// Byte 0: Header (always 0xD5)
// Byte 1: Fan speed secondary encoding
// Byte 2: Always 0x00
// Byte 3-5: Fixed suffix pattern (depends on fan speed and mode)
//
// TEMPERATURE ENCODING:
// Base temp codes: 18°C=0x10, 19°C=0x30, 20°C=0x20, 21°C=0x60, 22°C=0x70,
// 23°C=0x50, 24°C=0x40, 25°C=0xC0, 26°C=0xD0, 27°C=0x90,
// 28°C=0x80, 29°C=0xA0, 30°C=0xB0
// Mode offsets added to base temp:
// COOL: No offset
// HEAT: +0x0C (e.g., 24°C heat = 0x40 | 0x0C = 0x4C)
// AUTO: +0x08 (e.g., 24°C auto = 0x40 | 0x08 = 0x48)
// DRY: +0x24 (e.g., 24°C dry = 0x40 | 0x24 = 0x64)
//
// FAN SPEED ENCODING (First packet bytes 2-3):
// AUTO: 0xBF40, QUIET: 0xFF00, LOW: 0x9F60, MEDIUM: 0x5FA0, HIGH: 0x3FC0
// Special cases: AUTO/DRY modes use 0x1FE0 instead
//
// SINGLE-PACKET COMMANDS:
// Power Off: 0xC23D7B84E01F (6 bytes, no second packet)
// Swing Toggle: 0xC23D6B94E01F (6 bytes, no second packet)
//
// MODE DETECTION (from first packet):
// - Check bytes 2-3: if 0x7B84 → OFF mode
// - Check bytes 2-3: if 0x1FE0 → AUTO/DRY/low-temp-COOL (distinguish by temp code)
// - Otherwise: COOL/HEAT/FAN_ONLY (distinguish by temp code and byte 5)
