* design-systems/intercom/tokens.css
|
|
*
|
|
* Structured token bindings for "Design System Inspired by Intercom".
|
|
* Editorial customer-service warmth: warm cream canvas, off-black text,
|
|
* a single Fin Orange signal, and aggressively sharp 4px geometry.
|
|
*
|
|
* Key brand decisions encoded here:
|
|
* - Warm Cream (#faf9f6) canvas — never pure white, but white pops above it
|
|
* - Fin Orange (#ff5600) — the SINGULAR accent, named after Intercom's AI agent
|
|
* - Off Black (#111111) — warmer than #000, primary text + dark buttons
|
|
* - Oat (#dedbd6) borders — warm-tinted, never cool gray
|
|
* - Saans display: 80px at line-height 1.0 with -2.4px (≈ -0.03em) tracking
|
|
* - Sharp 4px radius — near-rectangular buttons are the geometric identity
|
|
*
|
|
* The "vivid purple/blue" hint sometimes associated with Intercom is the
|
|
* legacy Messenger SDK palette. The current intercom.com identity is
|
|
* warm-neutral + Fin Orange (see DESIGN.md §1, §2, §9), and that is what
|
|
* this token set encodes.

* Warm cream is the foundation — Intercom's website never uses pure
|
|
* white as the page background. Pure white IS used for the "lifted"
|
|
* surface tier so cards and panels punch above the warm canvas.
