Color as meaning — not decoration

The c/side mark stays monochrome-first (black, or white on black). A single accent is introduced only where it carries the story — either the resolved output or the model gate. The accent is wired to a CSS variable, so use the picker to compare palettes live. Recommended: Signal Coral — distinctive against the wall of security-blue.
