Decoded design system

Sellercentral's decoded design system: background #FFFFFF, text #0F1111, accent #FFD814, link #2162A1, primary #FFD814; type scale h1 20px / h2 20px / body 14px; 8px spacing base; 0px base radius. The single interactive/action color is #FFD814 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #FFD814 — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent, button_bg are all #FFD814 — one role, not several (the action color).
• accent #FFD814 — 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.
• link #2162A1 — inline text links and link-styled controls.

# Sellercentral — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F0F0F0` |
| border | `#DBDBDB` |
| text | `#0F1111` |
| text_muted | `#6A6B6B` |
| primary | `#FFD814` |
| accent | `#FFD814` |
| link | `#2162A1` |
| button_bg | `#FFD814` |
| button_text | `#0F1111` |

**Using these colors**

- **Action color** `#FFD814` — 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`, `button_bg` are all `#FFD814` — one role, not several (your action color).
- **accent** `#FFD814` — 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.
- **link** `#2162A1` — inline text links and link-styled controls.
- **Page coverage** (full-page screenshot pixels): `#FFFFFF` 95.4% · `#E1E4E6` 2.6% · `#FBDB3C` 1.1% · `#B9B696` 0.9%

## Typography

- Heading: **Arial**
- Body: **Arial**
- h1: 20px
- h2: 20px
- body: 14px

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

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 2px, 4px, 5px, 6px, 7px, 8px, 11px, 14px, 16px, 18px — snap all gaps/padding to these

## Radius
- base: 0px
- button: 0px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `rgba(0, 0, 0, 0)` / `#0F1111` | none | 0px | 5px 11px 5px 11px | 400 14px | none |

## Motion
- durations: 100ms (dominant)
- easings: `linear` (dominant)

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 |
|-------|-------|
| `--brand-teal` | `#007185` |
| `--brand-teal-alpha` | `rgba(0, 113, 133, 0.4)` |

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

## Layout (measured)

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 0 | 601 | — | — | 14/14 | — |

## Motion choreography (measured)
Load order: `input.a-input-text` @0ms → `input.a-input-text` @0ms → `input.a-input-text` @0ms → `input.a-input-text` @0ms → `input.a-input-text` @0ms → `input.a-input-text` @0ms

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

## Components (measured)
- input: h 32px · r 8px · border 1px solid rgb(33, 98, 161) · bg #FFFFFF · placeholder #0F1111

## Responsive (measured)
- breakpoints: 767px
- mobile (390px): hero 20px · body 14px · 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.
