  "description": "Cursor is an AI-first code editor — a fork of VS Code engineered around long-context model reasoning, project-wide edit operations, and an agentic terminal. The marketing surface at cursor.com reads as quietly editorial rather than loud-tech: a warm \"Sand\" near-paper canvas, deep \"Cursor Ink\" text, and a single hot \"Cursor Orange\" (#F54E00) accent. Product chrome inverts to a \"Cursor Night\" dark canvas with ANSI-aligned semantic greens and reds. Typography on the marketing site is Cursor's proprietary \"CursorGothic\" sans with a \"BerkeleyMono\" mono pair; neither is publicly distributed.\n",

The proprietary \"CursorGothic\" sans is declared via @font-face on cursor.com but is not publicly distributed; Inter is the open-source rendering substitute. The proprietary \"BerkeleyMono\" mono is not publicly distributed; JetBrains Mono Nerd Font is the open-source rendering substitute. Although Cursor's product chrome (the IDE itself) is dark-first, the marketing brand surface is light-first — `identity` is therefore mapped to the sand canvas rather than the night canvas.\n"
