## Overview

Harbor looks dependable without looking dull: a cool blue-grey page, navy for the main action, a bright blue for focus and data, and Plus Jakarta Sans for a modern but sober voice. Long feature pages, comparison tables and security sections fit with ease.

## Colors

- **primary (#13294B):** Navy, for primary buttons, the header and key figures. In dark mode it turns a light cornflower blue.
- **on-primary (#FFFFFF)**
- **secondary (#2F6FD6):** Bright blue, for focus rings, links in body copy and the second chart series.
- **tertiary (#18A0A0):** Teal, for success, integration badges and a third series.
- **neutral (#526077):** Slate blue-grey for descriptions, table headers and footnotes.
- **surface (#F6F8FB):** Cool blue-grey off-white; white cards hold content and screenshots.
- **on-surface (#0F1B2D)**

## Typography

Plus Jakarta Sans throughout: bold 700 for headings from a 60px display down to 20px with slightly tight tracking, regular 400 at 16px for body. JetBrains Mono for API snippets and figures in tables.

## Layout

A 12-column grid up to 1280px with 24px gutters and a 4px spacing unit. Pages follow a steady rhythm: hero, logo strip, feature rows that alternate text and screenshot, then proof and a closing call to action.

## Shapes

8px corners on cards, inputs and buttons. 1px borders in light blue-grey; soft, low shadows on cards, menus and the recommended pricing tier.

## Components

A mega-menu header, customer logo strip, feature rows with product screenshots, a plan comparison table, security and compliance badges, and a contact-sales form.

## Do's and Don'ts

- Do show the product with real screenshots, not abstract illustrations.
- Do back claims with customer logos, numbers and case studies.
- Don't let bright blue compete with the navy primary button.
- Don't hide pricing or the sales contact behind several clicks.
