Tokens

Twelve Labs's decoded design system: background #F5F5F5, text #1D1C1B, accent #5864ED, link #5864ED, primary #0000EE; type scale h1 48px / h2 48px / body 16px; 8px spacing base; 8px base radius. The single interactive/action color is #F4F3F3 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #F4F3F3 — the single interactive color; only on things you click or must notice, never large fills.
• accent, link are all #5864ED — one role, not several (the action color).
• accent #5864ED — accent for emphasis — keep it rare on the page.
• primary #0000EE — a brand color — but the call-to-action uses #F4F3F3, not this.
• secondary #30710E — 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.

# Twelve Labs — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#F5F5F5` |
| surface | `#E8E7E7` |
| border | `#D4D4D4` |
| text | `#1D1C1B` |
| text_muted | `#6F6E6D` |
| primary | `#0000EE` |
| accent | `#5864ED` |
| link | `#5864ED` |
| secondary | `#30710E` |
| button_bg | `#F4F3F3` |
| button_text | `#0000EE` |

**Using these colors**

- **Action color** `#F4F3F3` — 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 `#5864ED` — one role, not several.
- **accent** `#5864ED` — accent for emphasis — keep it rare on the page.
- **primary** `#0000EE` — a brand color — but the call-to-action uses #F4F3F3, not this.
- **secondary** `#30710E` — 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): `#050505` 55.3% · `#1D1C1B` 27.4% · `#DADADB` 10.9% · `#3E3C32` 6.3%

## Typography

- Heading: **Helvetica**
- Body: **Helvetica**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 48px / 400 · lh 56px · tracking -0.96px |
| h2 | 32px / 400 · lh 40px · tracking -0.64px |
| h3 | 20px / 400 · lh 28px · tracking 0.1px |
| body | 16px / 400 · lh 24px · tracking 0.16px |
| small | 14px / 400 · lh 18px |

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

> **Fonts —** Helvetica — system font, no web load needed.

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 4px, 8px, 10px, 16px, 18px, 20px, 24px, 32px, 40px, 56px — snap all gaps/padding to these

## Radius
- base: 8px
- button: 14px
- card: 12px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#000000` / `#F4F3F3` | 1px solid rgb(255, 255, 255) | 12px | 10px 18px 10px 18px | 500 14px | none |
| secondary | `#F4F3F3` / `#0000EE` | none | 18px | 18px 24px 18px 24px | 400 12px | none |

**States (measured, not guessed)**

- primary hover: background `#141414`
- primary focus: background `#141414` · outline `3px solid rgba(0, 65, 198, 0.8)`
- transition: `background-color 0.2s ease-out`

## Shadows (elevation)
- card: `rgba(29, 28, 27, 0.2) 0px 20px 24px -20px`
- overlay: `rgb(255, 211, 190) -20px -20px 60px 0px, rgb(191, 243, 164) 20px 2px 4px 0px`

## Motion
- durations: 200ms (dominant) · 700ms · 1000ms
- easings: `ease` (dominant) · `ease-out`
- animated properties: color, background-color, filter, 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 |
|-------|-------|
| `--osano-clear-dialog-background` | `rgba(226,226,226,0)` |
| `--osano-button-border-color` | `#fff` |
| `--osano-button-background-color` | `#000000` |
| `--osano-button-foreground-color` | `#FFFFFF` |
| `--osano-dialog-background-color` | `#e2e2e2` |
| `--osano-dialog-foreground-color` | `#000000` |
| `--osano-info-dialog-overlay-color` | `rgba(0,0,0,0.45)` |
| `--osano-link-color` | `#5864ed` |
| `--osano-toggle-off-track-color` | `#000000` |
| `--osano-toggle-off-thumb-color` | `#FFFFFF` |
| `--osano-toggle-on-track-color` | `#37CD8F` |
| `--osano-toggle-on-thumb-color` | `#FFFFFF` |

_…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: `div.osano-cm-info-dialog__in` @0ms → `div.osano-cm-window__dialog` @125ms → `button.osano-cm-dialog__close` @125ms → `button.osano-cm-dialog__close` @125ms → `button.osano-cm-dialog__close` @125ms → `button.osano-cm-dialog__close` @125ms
- `span` ×4 — color rgb(250, 186, 23)→rgb(96, 226, 27) — 200ms ease
- overlay dialog (auto-opened): panel #ECECEC · r 20px · shadow rgba(29, 28, 27, 0.2) 0px 20px 24px -20px

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

## Responsive (measured)
- breakpoints: 768px · 809px · 1199px
- mobile (390px): hero 28px · 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.
