Notion Calendar — Design System
Notion Calendar (née Cron) speaks the house dialect: Notion's cut of Inter at 64px/700 in soft black ('It's time.'), 16px body, and 8px-radius quiet buttons. Calendar UI in Notion's warm greys does all the showing — the acquisition absorbed the product into a design system so consistent the page needs almost no other brand.
