Decoded design system

Hopper Mobile's decoded design system: background #FFFFFF, text #111111, accent #01AAE4, link #01AAE4, primary #01AAE4; type scale h1 32px / h2 24px / body 16px; 4px spacing base; 12px base radius. The single interactive/action color is #002D11 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #002D11 — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent, link are all #01AAE4 — one role, not several (the action color).
• accent #01AAE4 — accent for emphasis — keep it rare on the page.

# Hopper Mobile — Design System

> light, consumer, high — deep decode (measured live)

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F0F0F0` |
| border | `#DBDBDB` |
| text | `#111111` |
| text_muted | `#6B6B6B` |
| primary | `#01AAE4` |
| accent | `#01AAE4` |
| link | `#01AAE4` |
| button_bg | `#002D11` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#002D11` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `primary`, `accent`, `link` are all `#01AAE4` — one role, not several.
- **accent** `#01AAE4` — accent for emphasis — keep it rare on the page.
- **Page coverage** (full-page screenshot pixels): `#FFFFFF` 21.4% · `#6F7882` 16.9% · `#ACBFCA` 16% · `#DCCCB3` 12.4%

## Typography

- Heading: **Proxima Nova** _(free fallback: Montserrat)_
- Body: **Proxima Nova** _(free fallback: Montserrat)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 32px / 800 · lh 40px |
| h2 | 24px / 700 · lh 32px |
| h3 | 22px / 700 · lh 24px |
| body | 16px / 400 · lh 24px |
| small | 14px / 400 · lh 20px |

- Weight ladder: 400 · 600 · 700 · 800 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** Proxima Nova is proprietary — closest free match: Montserrat (Google). Load Montserrat; keep Proxima Nova first so licensed users still get it.

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 4px, 6px, 8px, 10px, 12px, 16px, 20px, 24px, 25px, 32px — snap all gaps/padding to these

## Radius
- base: 12px
- button: 8px
- card: 8px
- pill: 9999px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#002D11` / `#FFFFFF` | none | 8px | 4px 16px 4px 16px | 700 14px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#FFFFFF` | 1px solid rgb(255, 255, 255) | 12px | 8px 24px 8px 24px | 600 16px | none |

**States (measured, not guessed)**

- primary hover: background `#00290F`
- primary focus: box-shadow `rgb(242, 250, 235) 0px 0px 0px 2px, rgb(0, 45, 17) 0px 0px 0px 4px`
- secondary hover: background `rgba(0, 0, 0, 0.03)`
- transition: `background-color 0.25s cubic-bezier(0.77, 0, 0.18, 1)`

## Shadows (elevation)
- card: `rgba(0, 0, 0, 0.25) 0px 4px 26px -7px`

## Motion
- durations: 250ms (dominant) · 300ms · 200ms
- easings: `cubic-bezier(0.77, 0, 0.18, 1)` (dominant) · `cubic-bezier(0.17, 0.84, 0.44, 1)`
- animated properties: background-color, color, box-shadow, border-color

Micro-interactions use the dominant duration + easing; nothing on the page animates slower than the longest duration above — don't invent springier motion.

## Their own tokens (verbatim from :root)

| Token | Value |
|-------|-------|
| `--white` | `#fff` |
| `--black` | `#000` |
| `--gray-05` | `#f5f5f5` |
| `--gray-10` | `#e7e7e7` |
| `--gray-20` | `#d9d9d9` |
| `--gray-30` | `#c3c3c3` |
| `--gray-40` | `#aaa` |
| `--gray-50` | `#939393` |
| `--gray-60` | `#767676` |
| `--gray-70` | `#545454` |
| `--gray-80` | `#383838` |
| `--gray-90` | `#232323` |

_…and 108 more measured on the page._

Prefer these names when extending their system — it's the brand's actual vocabulary.

## Motion choreography (measured)
Load order: `input.MuiInputBase-input`×10 @0ms → `select.MuiNativeSelect-select`×2 @2ms → `div.MuiStack-root` @2ms → `div.MuiStack-root` @2ms → `div.MuiStack-root`×2 @2ms → `div.MuiStack-root` @2ms

Rebuild the timeline, not just the durations — order, delays and staggers above are the choreography.

## Components (measured)
- input: h 23px · r 0px · bg rgba(0, 0, 0, 0) · placeholder #111111
- disabled: bg rgba(0, 0, 0, 0) · text rgba(0, 0, 0, 0.3)

## Responsive (measured)
- breakpoints: 375px · 480px · 744px · 992px · 1200px
- mobile (390px): body 16px · nav: inline

## How to apply
Paste the Tailwind `@theme` (or CSS variables) as your base, then build each
section to its spec — verify every color, radius, and font against these tokens.
Hover/focus states, shadows and motion timings above are measured from the live page — match them exactly, don't re-guess them.
