Decoded design system

Poe's decoded design system: background #FFFFFF, text #0D0D0D, accent #D7DBF4, link #413FA9, primary #413FA9; type scale h1 36px / h2 20px / body 20px; 4px spacing base; 10px base radius. The single interactive/action color is #D7DBF4 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #D7DBF4 — the single interactive color; only on things you click or must notice, never large fills.
• primary, link are all #413FA9 — one role, not several (the action color).
• accent, button_bg are all #D7DBF4 — one role, not several (the action color).
• accent #D7DBF4 — 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 #1A73E8 — 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.

# Poe — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F0F0F0` |
| border | `#DADADA` |
| text | `#0D0D0D` |
| text_muted | `#686868` |
| primary | `#413FA9` |
| accent | `#D7DBF4` |
| link | `#413FA9` |
| secondary | `#1A73E8` |
| button_bg | `#D7DBF4` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#D7DBF4` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `primary`, `link` are all `#413FA9` — one role, not several.
- `accent`, `button_bg` are all `#D7DBF4` — one role, not several (your action color).
- **accent** `#D7DBF4` — 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** `#1A73E8` — 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` 91.4% · `#C6CCC9` 2.8% · `#EDEEF5` 2.5% · `#8A8184` 2.3%

## Typography

- Heading: **Segoe UI** _(free fallback: Newsreader)_
- Body: **Segoe UI** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| body | 20px / 700 · lh 26px |
| small | 16px / 600 · lh 18px |

- Weight ladder: 400 · 450 · 500 · 600 · 700 — use these exact measured weights, not the 400/600 defaults.

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

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 6px, 8px, 12px, 14px, 16px, 20px, 30px — snap all gaps/padding to these

## Radius
- base: 10px
- button: 9999px
- card: 30px
- pill: 9999px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#D7DBF4` / `rgba(255, 255, 255, 0.5)` | 1px solid rgba(0, 0, 0, 0) | 9999px | 8px 16px 8px 16px | 600 16px | none |
| secondary | `#FFFFFF` / `#0D0D0D` | 1px solid rgb(204, 205, 209) | 9999px | 8px 16px 8px 16px | 600 16px | none |

**States (measured, not guessed)**

- secondary hover: background `color(srgb 0.917647 0.917647 0.933333 / 0.4)`
- transition: `background-color 0s ease`

## Shadows (elevation)
- card: `rgb(128, 128, 128) 0px 0px 5px 0px`

## Motion
- durations: 150ms (dominant) · 300ms
- easings: `ease` (dominant)
- animated properties: background-color, border-color, color, right

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 |
|-------|-------|
| `--pdl-comp-inline-notification-theme-warning-bg` | `#f8e6b4` |
| `--pdl-comp-radio-state-checked-fg` | `#5d5cde` |
| `--pdl-comp-attachment-image-border-color` | `#e3e3e7` |

| `--pdl-accent-base` | `#5d5cde` |
| `--color-accent-emphasis` | `#413fa9` |
| `--pdl-comp-switch-inner-state-disabled-bg` | `#f6f6f8` |
| `--pdl-comp-banner-theme-error-bg` | `#d00e49` |

_…and 108 more measured on the page._

Prefer these names when extending their system — it's the brand's actual vocabulary.

## Layout (measured)
- common grid: 2-col

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 0 | 900 | — | — | 0/0 | — |
| 160 | 740 | 2 | — | 0/0 | — |

## Motion choreography (measured)
Load order: `button.SocialLoginButton_button`×4 @0ms → `div.TextInput_wrapper__zvMrX`×2 @0ms → `button.Button_root__gehqi`×4 @0ms

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

## Components (measured)
- input: h 40px · r 0px · bg rgba(0, 0, 0, 0) · placeholder #757575
- link: #413FA9 · no underline
- disabled: bg #D7DBF4 · text rgba(255, 255, 255, 0.5)

## Themes (both measured)
- dark counterpart: bg `#101012` · text `#FCFCFC`
- tokens that flip between modes:
  - `--pdl-comp-inline-notification-theme-warning-bg`: `#f8e6b4` → `#805915`
  - `--pdl-comp-attachment-image-border-color`: `#e3e3e7` → `#303036`
  - `--yellow-11`: `#7b4f0d` → `#f5d47c`
  - `--shadow-black-dark`: `#00000080` → `#ffffff80`

  - `--ruby-7`: `#eb657c` → `#ab153d`
  - `--color-accent-emphasis`: `#413fa9` → `#8688fe`
  - `--pdl-comp-switch-inner-state-disabled-bg`: `#f6f6f8` → `#1b1b1e`

## Responsive (measured)
- breakpoints: 425px · 550px · 600px · 684px · 896px · 960px
- mobile (390px): hero 36px · body 16px · 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.
