Identity kit
The marks.
Every asset in the identity kit — the live wordmark, the archived C-dot masters at production sizes, the product icons, and the legibility tests. D15 (2026-10-11) retired the C-dot from live use after a collision with another SaaS mark; everything C-dot below is brand history, and the plain Curtis wordmark is the main logo.
