Rive — Design System

dark · modern · medium · custom · confidence 90% · deep decode

Rive animates in Tomorrow at 40px/500 on black — 'The Interactive experience engine' — with 14-16px working text and interactive Rive files embedded as living proof throughout. Characters blink, graphs respond, buttons morph; the page is a runtime demo where the typography's squared techno voice just labels the moving parts.

# Rive — Design System

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

Rive animates in Tomorrow at 40px/500 on black — 'The Interactive experience engine' — with 14-16px working text and interactive Rive files embedded as living proof throughout. Characters blink, graphs respond, buttons morph; the page is a runtime demo where the typography's squared techno voice just labels the moving parts.

## Colors

| Role | Value |
|------|-------|
| bg | `#000000` |
| surface | `#0F0F0F` |
| border | `#262626` |
| text | `#FFFFFF` |
| text_muted | `#9E9E9E` |
| primary | `#0000EE` |
| accent | `#FFA41C` |
| link | `#FFA41C` |
| button_bg | `#1A1A1A` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#1A1A1A` — 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 `#FFA41C` — one role, not several.
- **accent** `#FFA41C` — accent for emphasis — keep it rare on the page.
- **primary** `#0000EE` — a brand color — but the call-to-action uses #1A1A1A, not this.
- **Page coverage** (full-page screenshot pixels): `#000000` 73.4% · `#262626` 22.8% · `#68645C` 1.7% · `#1C1715` 1.2% — the action color covers ~1.2% of the page; keep it that scarce.

## Typography

- Heading: **Tomorrow** _(free fallback: Newsreader)_
- Body: **Tomorrow** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 40px / 500 · lh 48px · tracking 0.4px |
| h2 | 24px / 500 · lh 34px · tracking -0.8px |
| h3 | 20px / 500 · lh 24px · tracking 0.2px |
| body | 14px / 400 · lh 21px |
| small | 13px / 500 · lh 22px |
| eyebrow | 14px / 500 · tracking 0.7px |

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

> **Fonts —** Tomorrow may be proprietary — safe free fallback: Newsreader (Google Fonts).

## Spacing
- base unit: 10px (inferred from the measured scale)
- measured scale: 2px, 4px, 5px, 8px, 10px, 12px, 15px, 16px, 20px, 24px — snap all gaps/padding to these

## Radius
- base: 0px
- button: 8px
- card: 4px
- sharp: 3px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#1D1D1D` / `#0000EE` | none | 8px | 8px 10px 8px 10px | 400 12px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#0000EE` | none | 8px | 2px 2px 2px 2px | 400 12px | none |

**States (measured, not guessed)**

- primary hover: background `#222222`
- primary focus: outline `1px auto rgb(16, 16, 16)`

## Layout (measured)
- nav: 64px relative

## Motion choreography (measured)
- `span` ×2 — opacity 1→0 — 2200ms

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

## Components (measured)
- input: h 52.4062px · r 8px · bg #EBEBEB · placeholder rgba(0, 0, 0, 0.3)
- link: #999999 · underline — hover #FFFFFF

## Responsive (measured)
- breakpoints: 640px · 949px
- mobile (390px): hero 21px · body 12px · 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.
