Karyos Labs mark v2

Use black on light surfaces and white on dark surfaces. Do not recolour, stretch, crop, add shadows or alter the X.
SVG is preferred where accepted. The adaptive SVG switches black-on-white to white-on-black when the host supports prefers-color-scheme inside SVG images. A host that strips SVG styles cannot switch; use a static variant.
black/white files have transparent backgrounds; light/dark files have opaque white/black backgrounds. PNG and ICO cannot switch theme. Platform icons are fixed white-on-black, with separate maskable padding.
PNG sizes: 16, 32, 48, 64, 128, 256, 512, 1024, 2048. Pick the exact requested size or use SVG. Do not upscale a PNG. The X naturally loses detail at 16 px.
The approved master is karyos-logo-v2.svg (769 bytes). All other files are generated. inventory.json lists dimensions and SHA-256 digests. Site social cards are generated at build time from the same master geometry and current approved copy; they are not generic logo uploads.
