# Abhyudaya Sinha Design System

## Overview

Abhyudaya Sinha describes itself as: “Professional portfolio of Abhyudaya Sinha - Aspiring Data Analyst. Specializing in Python data cleaning, SQL relational queries, and interactive Power BI & Tableau dashboards. Focused on internship opportunities.” The interface is dark, built on **Cool Charcoal (#060814)** with **Light Blue (#CBD5E1)** text, and **Indigo (#6366F1)** as the main accent.

Type is set in **Outfit** and **Inter**, with **JetBrains Mono** for code. Headlines run large with tight negative tracking; body text is 16px. Depth comes from soft drop shadows. Corners are mostly 4px.

Measured from [personal-portfolio-c742e6.netlify.app](https://personal-portfolio-c742e6.netlify.app/) on November 3, 2026 at 1440×900 and 390×844 from 206 rendered elements. Values are computed styles from the live page, not the original source files.

## Typography

**Outfit**, **Inter** and **JetBrains Mono** (monospace) share the interface. Fallback stack: `Outfit, -apple-system, BlinkMacSystemFont, sans-serif`. Other loaded fonts: Fraunces, Font Awesome 6 Brands, Font Awesome 6 Free.

- **headline-display:** Outfit 61px at weight 800, line height 1.15, tracking -0.03em, uppercase (29px on mobile). Page title (h1).
- **headline-lg:** Outfit 45px at weight 800, line height 1.15, tracking -0.03em, uppercase (28px on mobile). Section headings (h2).
- **headline-md:** Inter 21.5px at weight 800, line height 1.15, tracking 0.05em, uppercase (20px on mobile). Sub-section headings.
- **headline-sm:** Outfit 20px at weight 800, line height 1.15, tracking -0.03em. Card and feature titles.
- **body-md:** Inter 16px at weight 400, line height 1.6, tracking -0.01em. Body text.

- **code:** JetBrains Mono 12.5px at weight 400, line height 1.6, tracking 0.06em. Code and technical values.

## Layout

Spacing does not follow a strict grid: 63% of measured values are multiples of 4px, so match the measured steps rather than rounding to a grid.

- **Scale:** xs 3px, sm 8px, md 16px, lg 20px, xl 48px.
- **Sections:** 48px vertical padding between major sections.
- **Gaps:** 8px is the most common gap in flex and grid layouts.
- **Container:** content is capped at 1200px.

## Elevation & Depth

Raised elements use soft drop shadows. The most used recipes:

- `rgba(99, 102, 241, 0.22) 0px 0px 22px 0px, rgba(0, 0, 0, 0.3) 0px 4px 12px 0px`
- `rgba(0, 0, 0, 0.45) 0px 8px 32px 0px, rgba(99, 102, 241, 0.05) 0px 0px 0px 1px, rgba(255, 255, 255, 0.04) 0px 1px 0px 0px inset`
- `rgba(99, 102, 241, 0.05) 0px 0px 0px 1px, rgba(0, 0, 0, 0.55) 0px 30px 80px 0px, rgba(99, 102, 241, 0.02) 0px 0px 120px 0px`

Hairline rings and inset highlights also appear: `rgba(34, 197, 94, 0.035) 0px 0px 0px 4.66482px`.

## Shapes

Most elements use 4px corners. Measured radii, most used first:

- **xs (4px):** 60 elements.
- **xl (100px):** 56 elements.
- **md (8px):** 48 elements.
- **lg (16px):** 48 elements.
- **full (9999px):** 16 elements.
- **sm (6px):** 12 elements.

## Components

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

- **button-primary (“GET IN TOUCH”):** #6366F1 fill, #000000 text, 12px/700, 100px radius, padding 8px 20px, border 1px solid #6366F1, shadow `rgba(99, 102, 241, 0.22) 0px 0px 22px 0px, rgba(0, 0, 0, 0.3) 0px 4px 12px 0px`.
- **button-primary-hover:** background #00000000, text #6366F1 on hover.
- **button-ghost (“DOWNLOAD RESUME”):** transparent fill, #FFFFFF text, 12.8px/700, 8px radius, padding 13.6px 24px, border 1px solid #FFFFFF12.
- **input-field (“John Doe”):** #040814 fill, #FFFFFF text, 14.4px/400, 8px radius, padding 12px, border 1px solid #6366F11F.
- **card:** transparent fill, #CBD5E1 text, 16px/400, 20px radius, padding 64px 48px, shadow `rgba(99, 102, 241, 0.05) 0px 0px 0px 1px, rgba(0, 0, 0, 0.55) 0px 30px 80px 0px, rgba(99, 102, 241, 0.02) 0px 0px 120px 0px`.
- **link:** transparent fill, #CBD5E1 text, padding 0px.

## Do's and Don'ts

- Do use #060814 for the page.
- Do keep text in 4 levels: #CBD5E1, #FFFFFF, #F8FAFC, #64748B.
- Do reserve #6366F1 for primary actions and key highlights.
- Do set headlines in Outfit with tight tracking (-0.03em).
- Do reuse the measured spacing steps (8px, 16px, 20px).
- Do use 4px corners on most elements; larger surfaces also use 100px, 8px and 16px.
- Don't use #64748B for body text; it reaches 4.19:1 on #060814. Keep it for large text or metadata.
- Don't introduce new font families beyond Outfit, Inter and JetBrains Mono.
- Don't use #6366F1 for large backgrounds or body text.
- Don't make interface transitions slower than 0.4s.

## Motion

Interface transitions are quick: 0.2s, 0.35s, 0.4s. Longer ambient animations run 2s.

- **Easing:** `ease`, `cubic-bezier(0.16, 1, 0.3, 1)`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
