HEY yells like its name: Really Sans Large at 83px/900 in ink-purple #231C33 ('We finally fixed your email + calendar!'), body copy at a conversational 24-27px, and Moniker on 52px-pill buttons. Hand-drawn arrows, marker highlights and screenshot walkthroughs make the page read like an enthusiastic product demo by its founders — because it is.

# Hey — Design System

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

HEY yells like its name: Really Sans Large at 83px/900 in ink-purple #231C33 ('We finally fixed your email + calendar!'), body copy at a conversational 24-27px, and Moniker on 52px-pill buttons. Hand-drawn arrows, marker highlights and screenshot walkthroughs make the page read like an enthusiastic product demo by its founders — because it is.

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F1F1F2` |
| border | `#DEDCE0` |
| text | `#231C33` |
| text_muted | `#767280` |
| primary | `#B3F4E0` |
| accent | `#5522FA` |
| link | `#231C33` |
| secondary | `#5522FA` |
| button_bg | `#5522FA` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#5522FA` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `secondary`, `button_bg` are all `#5522FA` — one role, not several (your action color).
- **accent** `#5522FA` — 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** `#B3F4E0` — a brand color — but the call-to-action uses #5522FA, not this.
- **link** `#231C33` — inline text links and link-styled controls.
- **Page coverage** (full-page screenshot pixels): `#FFFFFF` 68.6% · `#7546BC` 8.7% · `#A079BF` 7.4% · `#F1EFF0` 5.5%

## Typography

- Heading: **Moniker** _(free fallback: Newsreader)_
- Body: **Really Sans Large** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 83px / 900 · lh 92px |
| h2 | 48px / 850 · lh 53px |
| h3 | 40px / 850 · lh 48px |
| body | 18px / 700 · lh 26px · tracking -0.22px |
| small | 14px / 500 · lh 14px · tracking -0.18px |

- Weight ladder: 400 · 500 · 700 · 850 · 900 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** Moniker may be proprietary — safe free fallback: Newsreader (Google Fonts). Really Sans Large may be proprietary — safe free fallback: Newsreader (Google Fonts).

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 4px, 6px, 9px, 13px, 16px, 19px, 21px, 27px, 32px, 45px — snap all gaps/padding to these
- section rhythm: 40px top/bottom padding per section (measured)

## Radius
- base: 21px
- button: 68px
- card: 68px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `rgba(0, 0, 0, 0)` / `#FFFFFF` | none | 60px | 0px 0px 0px 0px | 500 24px / -0.42px | rgba(255, 255, 255, 0.1) 0px 2.4px 28.8px 0px, rgba(255, 255, 255, 0.1) 0px 4.8px 38.4px 0px, rgba(255, 255, 255, 0.1) 0px 7.2px 48px 0px |
| secondary | `#FFFFFF` / `#FFFFFF` | none | 68px | — | — | none |

**States (measured, not guessed)**

- transition: `color 0.15s cubic-bezier(0.37, 1, 0.74, 1)`

## Shadows (elevation)
- card: `rgba(35, 28, 51, 0.1) 0px 25.6px 12.8px -25.6px, rgba(35, 28, 51, 0.15) 0px 38.4px 25.6px -38.4px, rgba(35, 28, 51, 0.2) 0px 51.2px 38.4px -51.2px`
- overlay: `rgba(255, 255, 255, 0.1) 0px 2.4px 28.8px 0px, rgba(255, 255, 255, 0.1) 0px 4.8px 38.4px 0px, rgba(255, 255, 255, 0.1) 0px 7.2px 48px 0px`

## Motion
- durations: 150ms (dominant) · 300ms
- easings: `cubic-bezier(0.37, 1, 0.74, 1)` (dominant)
- animated properties: color, transform, text-decoration-color, text-decoration-thickness

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