16-bit LZW TIFFs come out larger than uncompressed ones and slower than ZIP. The export keeps LZW exactly as picked (some software reads only LZW), and says what it costs where it is chosen: - Export dialog: a note under Compression when LZW is selected, worded more strongly at 16 bit, a milder one at 8 bit and 32-bit float. - Export presets that write LZW TIFFs carry the same hint on hover, in the dialog's Preset list and the grid's Export with Preset menu. - tiffCompression docs: MCP schema and headless params, the user export guide and the parity checklist. Tests: the note shows for LZW only and under the Compression choice (headless), presets get the same hint, the dialog keeps LZW; 16-bit ZIP is never larger than uncompressed on a noisy synthetic render (noise 0 to 0.1) and on the demo photo's export.
