# ProSystem Design System

## Overview

ProSystem describes itself as: “ProSystem Limited - Bangladesh-based IT-enabled services company developing business management system, eCommerce and custom application for 30+ businesses and 200,000+ users worldwide.” The interface is light, built on **White (#FFFFFF)** with **Near Black (#0A0A0B)** text, and **Vivid Blue (#3581F6)** as the main accent.

Type is set in **neueHaas** and **Roboto**. Headlines run large; body text is 16px. Depth comes from hairline borders and inset highlights rather than drop shadows. Controls are pill-shaped.

Measured from [prosystem.com.bd](https://www.prosystem.com.bd/) on November 7, 2026 at 1440×900 and 390×844 from 402 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 17 roles.

- **White (#FFFFFF):** Page background, seen 2 times. Token `background`, CSS `--tw-ring-offset-color`.
- **Near Black (#0A0A0B):** Primary text and headings, seen 96 times. Token `on-surface`.
- **Slate (#676768):** Secondary text, seen 6 times. Token `on-surface-variant`.
- **Slate (#737373):** Muted text and metadata, seen 2 times. Token `on-surface-muted`.
- **Snow (#FDFCFC):** Raised areas one step from the page, seen 31 times. Token `surface-container-low`.
- **Snow (#F9F9F9):** Cards and panels, seen 1 time. Token `surface-container`.
- **Snow (#F6F6F6):** Hover and pressed fills, seen 1 time. Token `surface-container-high`.
- **Mist (#EBEBEB):** Highest raised elements, seen 2 times. Token `surface-container-highest`.
- **White 10% (#FFFFFF1A):** Translucent fill for cards and controls, seen 5 times. Token `overlay`.
- **White 35% (#FFFFFF59):** Stronger translucent fill, seen 4 times. Token `overlay-strong`.
- **Near Black 5% (#0A0A0B0D):** Borders and dividers, seen 3 times. Token `outline`.
- **Near Black 9% (#0A0A0B17):** Secondary dividers, seen 2 times. Token `outline-variant`.
- **Vivid Blue (#3581F6):** Brand color on large areas, seen 9 times. Token `primary`.
- **Snow (#F8F8F8):** Text and icons on primary. Token `on-primary`.
- **Charcoal (#171717):** High-contrast fills, seen 1 time. Token `inverse-surface`.
- **Blue (#50A2FF):** Accent on large areas. Token `secondary`.
- **Light Blue (#8EC5FF):** Accent on large areas. Token `tertiary`.

## Typography

**neueHaas** and **Roboto** share the interface. Fallback stack: `neueHaas, neueHaas Fallback`.

- **headline-display:** neueHaas 30px at weight 400, line height 1.2. Page title (h1).
- **body-md:** Roboto 16px at weight 400, line height 1.5. Body text.
- **body-lg:** Roboto 18px at weight 400, line height 1.56. Lead paragraphs.
- **body-sm:** Roboto 14px at weight 400, line height 1.43. Secondary and small text.
- **caption:** Roboto 12px at weight 400, line height 1.38. Captions and fine print.
- **label-lg:** Roboto 15px at weight 500, line height 1.43, tracking -0.025em. Large buttons and tabs.
- **label-md:** Roboto 14px at weight 700, line height 1, tracking -0.025em. Buttons, navigation and labels.
- **label-sm:** Roboto 13px at weight 500, line height 1.5. Small labels and badges.

## Layout

Spacing is mostly on a 4px grid (81% of measured values), with some off-grid steps. Match the measured scale rather than rounding everything.

- **Scale:** xs 2px, sm 8px, md 16px, lg 20px, xl 64px.
- **Sections:** 88px vertical padding between major sections.
- **Gaps:** 16px is the most common gap in flex and grid layouts.
- **Breakpoints:** 359.98px, 360px, 375px, 390px, 400px, 499.98px, 640px, 768px.

## Elevation & Depth

The design avoids drop shadows. Layers are separated by tonal surface steps (#FDFCFC → #F9F9F9 → #F6F6F6 → #EBEBEB) and hairline rings:

- `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, oklab(0 0 0 / 0.075) 0px 0px 0px 0.5px inset, rgba(0, 0, 0, 0) 0px 0px 0px 0px`
- `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, oklab(0.999994 0.0000455678 0.0000200868 / 0.1) 0px 0px 0px 0.5px inset, rgba(0, 0, 0, 0) 0px 0px 0px 0px`

## Shapes

Interactive controls are pill-shaped. Measured radii, most used first:

- **sm (8px):** 20 elements.
- **lg (28px):** 16 elements.
- **full (9999px):** 16 elements.
- **md (24px):** 6 elements.

## Components

Measured from the rendered page. Token values reference the tokens above.

- **button-primary (“Sign In”):** #3581F6 fill, #F8F8F8 text, 16px/400, 8px radius, padding 0px.
- **button-ghost (“Sign In”):** transparent fill, 14px/500, 8px radius, padding 0px 10px.
- **input-field (“you@company.com”):** transparent fill, #0A0A0B text, 16px/400, padding 0px.
- **link:** transparent fill, #0A0A0B text, padding 0px.

## Do's and Don'ts

- Do use #FFFFFF for the page and lift surfaces in small steps: #FDFCFC, #F9F9F9, #F6F6F6, #EBEBEB.
- Do keep text in 3 levels: #0A0A0B, #676768, #737373.
- Do use #3581F6 as the brand accent: header, logo and key highlights.
- Do reuse the measured spacing steps (8px, 16px, 20px).
- Do make buttons and chips fully rounded (9999px); most other elements use 8px corners.
- Don't add drop shadows for depth; use hairline rings and tonal surfaces.
- Don't introduce new font families beyond neueHaas and Roboto.
- Don't use #3581F6 for large backgrounds or body text.
- Don't make interface transitions slower than 0.55s.

## Motion

Interface transitions are quick: 0.2s, 0.55s, 0.3s, 0.4s.

- **Easing:** `ease`, `cubic-bezier(0.25, 0.46, 0.45, 0.94)`, `cubic-bezier(0.4, 0, 0.2, 1)`.
