# TRIONN Design System

## Overview

TRIONN describes itself as: “TRIONN is an independent AI-powered digital studio crafting meaningful brand experiences through strategy, design, and technology. Based in Rajkot, Gujarat, India, we create premium websites, immersive digital products, ” The interface is dark, built on **Charcoal (#0C0C0C)** with **Silver (#D8D8D8)** text and almost no color: actions are carried by contrast, not hue.

Type is set in **familjen** and **neueHaas**, with **martianMono** for code. Headlines run large with tight negative tracking; body text is 14.5px. The surface language is flat. Corners are mostly 7.2px.

Measured from [trionn.com](https://trionn.com/) on November 6, 2026 at 1440×900 and 390×844 from 306 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 11 roles.

- **Charcoal (#0C0C0C):** Page background. Token `background`.
- **Silver (#D8D8D8):** Primary text and headings, seen 44 times. Token `on-surface`, CSS `--color-light-font`.
- **White (#FFFFFF):** Headings and emphasis, seen 6 times. Token `on-surface-strong`, CSS `--white`.
- **Graphite (#434343):** Secondary text, seen 17 times. Token `on-surface-variant`, CSS `--pl-line-gray`.
- **Near Black (#040508):** Raised areas one step from the page, seen 3 times. Token `surface-container-low`, CSS `--bg`.
- **Graphite (#272727):** Cards and panels, seen 1 time. Token `surface-container`.
- **Cool Graphite (#2F3135):** Hover and pressed fills, seen 1 time. Token `surface-container-high`.
- **Near Black 20% (#00000033):** Translucent fill for cards and controls, seen 6 times. Token `overlay`.
- **Graphite 15% (#43434326):** Stronger translucent fill, seen 4 times. Token `overlay-strong`.
- **White (#FFFFFF):** Primary buttons and calls to action, seen 18 times. Token `primary`, CSS `--white`.
- **Near Black (#000000):** Text and icons on primary. Token `on-primary`.

## Typography

**familjen**, **neueHaas** and **martianMono** (monospace) share the interface. Fallback stack: `familjen, familjen Fallback, sans-serif`.

- **headline-display:** familjen 90px at weight 400, line height 0.9, tracking -0.06em (46px on mobile). Page title (h1).
- **headline-lg:** familjen 85.5px at weight 400, line height 0.95, tracking -0.06em (30.5px on mobile). Section headings (h2).
- **headline-md:** familjen 32.5px at weight 400, line height 1, tracking -0.04em (21px on mobile). Sub-section headings.
- **body-md:** neueHaas 14.5px at weight 400. Body text.
- **body-lg:** neueHaas 16px at weight 400. Lead paragraphs.
- **code:** martianMono 12.5px at weight 400, tracking -0.06em, uppercase. Code and technical values.

## Layout

Spacing does not follow a strict grid: 33% of measured values are multiples of 4px, so match the measured steps rather than rounding to a grid.

- **Scale:** sm 7.2px, md 14.4px, lg 21.6px, xl 36px.
- **Sections:** 108px vertical padding between major sections.
- **Gaps:** 21.6px is the most common gap in flex and grid layouts.
- **Container:** content is capped at 1440px.
- **Breakpoints:** 440px, 640px, 677px, 768px, 1024px, 1280px, 1441px, 1536px.

## Elevation & Depth

The design is flat: no shadows were measured. Hierarchy comes from tonal surface steps (#040508 → #272727 → #2F3135).

## Shapes

Most elements use 7.2px corners. Measured radii, most used first:

- **md (7.2px):** 48 elements.

## Components

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

- **button-primary (“L E T ' S T A L K L E T ' S T A ”):** #FFFFFF fill, #000000 text, 15.3072px/400, 3.35544e+07px radius, padding 5.4px 14.4px 7.2px 14.4px, border 1px solid #FFFFFF.
- **button-ghost (“D I S C U S S   Y O U R   P R O ”):** transparent fill, #D8D8D8 text, 12.6px/400, padding 0px.
- **card:** #272727 fill, #D8D8D8 text, 14.4px/400, 7.2px radius, padding 0px.
- **link:** transparent fill, #D8D8D8 text, padding 0px.

## Do's and Don'ts

- Do use #0C0C0C for the page and lift surfaces in small steps: #040508, #272727, #2F3135.
- Do keep text in 3 levels: #D8D8D8, #FFFFFF, #434343.
- Do let contrast carry emphasis; primary actions use #FFFFFF on #0C0C0C.
- Do set headlines in familjen with tight tracking (-0.06em).
- Do reuse the measured spacing steps (7.2px, 14.4px, 21.6px).
- Do use 7.2px corners on most elements.
- Don't use #434343 for body text; it reaches 1.98:1 on #0C0C0C. Keep it for large text or metadata.
- Don't add drop shadows for depth; use tonal surfaces.
- Don't introduce new font families beyond familjen, neueHaas and martianMono.
- Don't add saturated accent colors; the measured palette is almost entirely neutral.
- Don't make interface transitions slower than 0.5s.

## Motion

Interface transitions are quick: 0.5s, 0.3s, 0.33s, 0.36s. Longer ambient animations run 0.7s.

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