Decoded design system

June's decoded design system: background #FFFFFF, text #343A40, accent #2A2A63, link #2A2A63, primary #151531; type scale h1 60px / h2 40px / body 16px; 8px spacing base; 8px base radius. The single interactive/action color is #2A2A63 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

# June — Design System

> light, professional, medium, custom — deep decode (measured live)

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F2F3F3` |
| border | `#E0E1E2` |
| text | `#343A40` |
| text_muted | `#818488` |
| primary | `#151531` |
| accent | `#2A2A63` |
| link | `#2A2A63` |
| secondary | `#EFF6FF` |
| button_bg | `rgba(0, 0, 0, 0)` |
| button_text | `#151531` |

**Using these colors**

- **Action color** `#2A2A63` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `link` are all `#2A2A63` — one role, not several (your action color).
- **accent** `#2A2A63` — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
- **primary** `#151531` — a brand color — but the call-to-action uses #2A2A63, not this.
- **secondary** `#EFF6FF` — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
- **Page coverage** (full-page screenshot pixels): `#FAFAFA` 94.7% · `#B4B4C9` 5.3%

## Typography

- Heading: **SF Pro Rounded** _(free fallback: Nunito Sans)_
- Body: **SF Pro Rounded** _(free fallback: Nunito Sans)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 60px / 900 · lh 60px |
| h2 | 40px / 900 · lh 50px |
| h3 | 24px / 700 · lh 28px |
| body | 16px / 400 · lh 24px |
| small | 14px / 900 · lh 20px · tracking 0.35px |
| eyebrow | 14px / 900 · tracking 0.35px |

- Weight ladder: 400 · 700 · 900 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** SF Pro Rounded is proprietary — closest free match: Nunito Sans (Google). Load Nunito Sans; keep SF Pro Rounded first so licensed users still get it.

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 8px, 13px, 16px, 24px, 32px, 48px, 64px, 127px — snap all gaps/padding to these

## Radius
- base: 8px
- button: 0px
- card: 12px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |

**States (measured, not guessed)**

- primary focus: outline `1px auto rgb(16, 16, 16)`

## Shadows (elevation)

## 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.
