Cal.com — Style Reference

> A clean, calendar-software-first interface anchored on white canvas with black primary CTAs and custom Cal Sans display typography. The system reads as friendly modern SaaS — generous whitespace, soft-rounded cards (~12px), product UI fragments shown directly inside cards, and a dark navy footer that visually closes long-scroll pages. Brand voltage comes from the Cal Sans display headline (a custom geometric face) and from product UI artifacts shown in-card rather than from accent colors.

  • Use `--color-primary` for the brand's primary interaction treatment.
  • Keep page surfaces anchored to `--color-canvas`.
  • Preserve every typography style's documented size, line height, and letter spacing.
  • Compare major implementation decisions against [the live Cal.com website](https://cal.com/).

    • Don't

  • Do not introduce colors outside the documented color token set.
  • Do not replace `--color-ink` with an arbitrary neutral.
  • Do not flatten documented component states or spacing relationships.
  • Do not treat this extracted snapshot as newer than the live source website.

    • Layout

    Use the documented spacing scale and component geometry as the implementation baseline. Validate responsive composition and current page rhythm against [the live source](https://cal.com/).
