This is expected to yield significant savings. + - *Status*: Deferred until feature completion. +- **CRT Replacement**: Consider replacing the standard C runtime (CRT) with a minimal startup code (e.g., `tiny_crt` or similar) to avoid linking heavy standard libraries. +- **Import Minimization**: Dynamically load functions via `GetProcAddress` hash lookup to reduce the Import Address Table (IAT) size. + +### General +- **Shader Compression**: Minify WGSL shaders (remove whitespace, rename variables). +- **Asset Compression**: + - Store spectrograms with logarithmic frequency bins. + - Quantize spectral values to `uint16_t` or `uint8_t`. + - Use a custom packer/compressor for the asset blob.
