Tokens

Microsoft Teams Mobile's decoded design system: background #FFFFFF, text #2F2B3E, accent #303AA7, link #303AA7, primary #303AA7; type scale h1 34px / h2 22px / body 17px; 8px spacing base; 12px base radius. The single interactive/action color is #303AA7 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FFFFFF`
surface	`#F2F2F3`
border	`#DFDFE2`
text	`#2F2B3E`
text_muted	`#7E7B87`
primary	`#303AA7`
accent	`#303AA7`
link	`#303AA7`
button_bg	`#303AA7`
button_text	`#FFFFFF`

Using these colors

Action color #303AA7 — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, link, button_bg are all #303AA7 — one role, not several (the action color).
accent #303AA7 — 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.

# Microsoft Teams Mobile — Design System

> light, consumer, high — deep decode (measured live)

Microsoft Teams Mobile — palette measured from official store listing screenshots (colors only; no font claims). Type scale shown is the platform HIG default.

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F2F2F3` |
| border | `#DFDFE2` |
| text | `#2F2B3E` |
| text_muted | `#7E7B87` |
| primary | `#303AA7` |
| accent | `#303AA7` |
| link | `#303AA7` |
| button_bg | `#303AA7` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#303AA7` — 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 `#303AA7` — one role, not several (your action color).
- **accent** `#303AA7` — 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.
- **Page coverage** (full-page screenshot pixels): `#F6F3F7` 98.3% · `#D8DEEA` 1.7%

## Typography

- h1: 34px
- h2: 22px
- body: 17px

## Spacing
- base unit: 8px
- scale: 4px, 8px, 12px, 16px, 24px, 32px, 48px, 64px

## Radius
- base: 12px
- button: 12px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#0067B8` / `#FFFFFF` | none | 12px | 4px 12px 4px 12px | 400 15px | none |

**States (measured, not guessed)**

- primary hover: background `#005DA6`
- primary focus: background `#005DA6` · outline `2px solid rgb(0, 0, 0)`

## Shadows (elevation)
- card: `rgba(0, 0, 0, 0.2) 0px 2px 6px 0px`

## Motion
- durations: 250ms (dominant) · 300ms · 500ms
- easings: `ease-in` (dominant) · `ease`

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

## Layout (measured)

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 0 | 900 | — | — | 0/0 | — |

## Motion choreography (measured)
Load order: `div.lightbox-cover` @0ms → `div.lightbox-cover` @0ms → `div.sign-in-box` @128ms → `div.background-image` @128ms → `div`×2 @206ms → `div.pagination-view` @350ms
- `div.pagination-view` — opacity 0→1 — 250ms cubic-bezier(0.5, 0, 0.5, 1)

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

## Components (measured)
- input: h 36px · r 0px · bg rgba(0, 0, 0, 0) · placeholder rgba(0, 0, 0, 0.6)

## Responsive (measured)
- breakpoints: 320px · 539px · 768px · 992px · 1400px
- mobile (390px): body 15px · 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.
