Dark, monochrome marketing site led by large product UI renders; tiered pricing table; sign-up page with a minimal centered auth card.

### Analysis (ours)
Captured linear.app: near-black canvas (#08090A ESTIMATED), large white headline and a product-UI render as the hero visual; pricing is a dark four-column table; sign-up is a small centered card. Accent color is almost absent.

### In-app patterns (observed)
- **App shell layout:** Persistent left sidebar (~130px of a 1024px viewport) on a slightly darker gray than the main canvas; the content area is an inset rounded panel with a header row (breadcrumb + actions) and a view-tab row. A slim bottom bar holds help and Agent shortcuts.
- **Sidebar navigation:** Personal items first (Inbox with an unread count, My issues, Agent), then collapsible groups: Workspace, Your teams (team → Home / Issues / Projects / Views) and Try (import, invite, connect GitHub). Small 14px icons, compact rows, active row as a soft gray pill.
- **Density:** High information density: ~23px issue rows in the captured list (ID, status icon, title, assignee avatar, date), small type and tight spacing; color is reserved for status and the purple primary actions.
- **Command menu pattern:** Ctrl+K opens a centered palette over the current view: one input (“Type a command or search…”, plus “Ask Linear”), results grouped by object type, each row with an icon and its single-key or chord shortcut (C, V, N then P). It teaches shortcuts while you search.
- **Empty state pattern:** A monochrome line-art illustration, one sentence (“No issues assigned to you”) and a single primary CTA. Filter chips (Assigned / Created / Subscribed / Activity) stay visible, so the user keeps their bearings.
- **Modal pattern:** Issue creation is a centered card over a dimmed shell: breadcrumb (team › New issue), large borderless title field, description, a row of property chips, expand and close icons, plus a “Create more” toggle for batch entry and one primary button.
- **Onboarding pattern:** Five dark split-screen steps after workspace creation: a short form on the left, blurred product art on the right, progress dots, and Skip on every step; integrations (GitHub, Slack) are offered but optional.
- **Theme system:** Preferences offer System preference, Light, Pure Light, Dark and more, each previewed with an “Aa” chip; a separate Code theme follows the interface theme unless overridden. Light and dark keep identical layouts; only surfaces and text tokens swap.

## Layout rules
- Observed layout pattern: **Split hero** (from our captures).
- Public flow (captured, stopped before any form submission): Landing (https://linear.app/) → Pricing (https://linear.app/pricing) → Sign-up entry (https://linear.app/signup)

## Do’s and don’ts
- Do: Use a near-black canvas with high-contrast white text and at most one accent.
- Don’t: Don’t add multiple saturated accents or light-mode shadows.
- Do: follow the source’s license/terms listed above.
- Don’t: present ESTIMATED colors as official tokens.
