Built entirely in the browser. JPEG decoded via hand-written WAT/WASM with SIMD v128 (0xFD prefix). Full decodeScan in WAT: bitstream reader, Huffman decoder, DC/AC coefficient decode, zigzag reorder, SIMD f32x4.mul (0xFD 0xE6) dequantization, SIMD f32x4 IDCT butterfly operations (f32x4.add 0xFD 0xE4, f32x4.splat 0xFD 0x13, f32x4.extract_lane 0xFD 0x1F), v128.store (0xFD 0x0B) batch memory init, v128.const (0xFD 0x0C). DCT cosine tables computed via Taylor series in WAT.
