Coval
A warm-editorial, near-monochrome interface for a voice-AI evaluation platform, built on a soft off-white paper canvas (#f2f1ee) with slightly warmer card surfaces (#fdfcf8), near-black pill CTAs, and a single geometric grotesque (PP Mori) carrying everything from oversized display headlines down to body copy. The system reads as calm, technical, and confident — generous vertical whitespace, low-chroma neutrals, product dashboard fragments shown inside soft-shadowed cards, and a stippled dot field as the only decorative texture. Brand voltage comes from the huge weight-400 display type and the warm paper palette rather than from accent color.
