Loom now speaks Atlassian: Charlie Display at 63px/700 in ink #101214, Charlie Text at 16px, and Atlassian blue #1868DB doing the linking. Video thumbnails with real faces are the hero imagery — 'one video is worth a thousand words' backed by an autoplay player — while bento panels tally AI workflows; async video tooling folded neatly into an enterprise design language.

Tokens

Loom's decoded design system: background #FFFFFF, text #0A0A0B, accent #1868DB, link #1868DB, primary #1868DB; type scale h1 70px / h2 48px / body 28px; 4px spacing base; 12px base radius. The single interactive/action color is #1868DB — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

# Loom — Design System

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

Loom now speaks Atlassian: Charlie Display at 63px/700 in ink #101214, Charlie Text at 16px, and Atlassian blue #1868DB doing the linking. Video thumbnails with real faces are the hero imagery — 'one video is worth a thousand words' backed by an autoplay player — while bento panels tally AI workflows; async video tooling folded neatly into an enterprise design language.

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F0F0F0` |
| border | `#DADADA` |
| text | `#0A0A0B` |
| text_muted | `#676767` |
| primary | `#1868DB` |
| accent | `#1868DB` |
| link | `#1868DB` |
| secondary | `#F8EEFE` |
| button_bg | `#1868DB` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#1868DB` — 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`, `button_bg` are all `#1868DB` — one role, not several (your action color).
- **accent** `#1868DB` — 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.
- **secondary** `#F8EEFE` — 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): `#FFFFFF` 62.4% · `#B6C5CD` 13.5% · `#8A999B` 8.7% · `#5E6C72` 7.5%

## Typography

- Heading: **Charlie Display** _(free fallback: Newsreader)_
- Body: **Charlie Text** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 63px / 700 · lh 65px |
| h2 | 44px / 700 · lh 50px |
| h3 | 33px / 700 · lh 41px |
| body | 19px / 400 · lh 31px |
| small | 18px / 700 · lh 27px |

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

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

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 8px, 12px, 16px, 23px, 32px, 36px, 47px, 64px, 71px — snap all gaps/padding to these
- section rhythm: 111px top/bottom padding per section (measured)

## Radius
- base: 12px
- button: 9999px
- card: 42px
- pill: 9999px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#1868DB` / `#FFFFFF` | none | 9999px | 7.80769px 15.6154px 7.80769px 15.6154px | 400 15.6154px | none |
| secondary | `#E9F2FE` / `#000000` | none | 9999px | — | — | none |

**States (measured, not guessed)**

- primary hover: transform `matrix(1.01, 0, 0, 1.01, 0, -1.56154)`
- transition: `transform 0.1s ease-in-out`

## Shadows (elevation)
- card: `rgba(0, 0, 0, 0.04) 0px 2px 6px 0px, rgba(0, 0, 0, 0.06) 0px 5px 18px 0px, rgba(0, 0, 0, 0.1) 0px 24px 83px 0px`
- overlay: `rgba(0, 0, 0, 0.25) 0px 15px 50px 0px`

## Motion
- durations: 100ms (dominant) · 300ms · 500ms
- easings: `ease-in-out` (dominant) · `ease`
- animated properties: background-color, transform, color, 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.

## 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.
